How China has established it Dash Line Claims of South China Sea over time?

The South China Sea’s new ten-Dash Line, transformed from the nine-dash line, which was first delineated on a Chinese map in 1947, has emerged as a central and contentious element in global geopolitical dialogues. In July 2016, an international tribunal, the Permanent Court of Arbitration in The Hague, delivered a landmark ruling, declaring that China’s use of the Nine-Dash Line to assert historical rights over the South China Sea had no legal basis. Despite this judgment, China maintained its territorial claims, further intensifying regional tensions. The Nine-Dash Line’s scope covers a wide expanse, including various islands, shoals, and reefs claimed by multiple nations. The line’s deliberate ambiguity has complicated discussions surrounding sovereignty and maritime rights in the South China Sea, leading to ongoing disputes and diplomatic challenges. China’s recent publication of a new national map featuring a “10-dash line” has reignited concerns and raised questions about the region’s future.

Defining the Nine-Dash Line

The nine-dash line, sometimes referred to as the eleven-dash line by Taiwan, has been a source of ongoing tension and disputes in the South China Sea. It represents a set of line segments on various maps used to assert the territorial claims by the People’s Republic of China (PRC) in the South China Sea. The contested area encompasses a vast expanse, including the Paracel Islands, the Spratly Islands, the Pratas Island, the Macclesfield Bank, the Scarborough Shoal, and the Vereker Banks. These territories have been subject to land reclamation efforts by various countries, including China, Taiwan, and Vietnam. The nine-dash line’s ambiguity continues to be a source of concern and a focal point in discussions surrounding sovereignty and maritime rights in the South China Sea.

China’s Stance and Actions

The history of the nine-dash line is intricate, with its evolution spanning several decades. It was originally introduced as an eleven-dash line in a map published by the Republic of China in 1947. However, in 1952, two dashes were removed from the Gulf of Tonkin, seen as a diplomatic concession to North Vietnam. This transformation in the line, initially consisting of eleven dashes, was influenced by political shifts and goodwill gestures, notably Chairman Mao Zedong’s decision to relinquish claims in the Gulf of Tonkin. This highlights how diplomacy played a pivotal role in shaping the line and underscores its adaptability in response to changing diplomatic relations, leading to tensions and disputes with neighboring countries such as Vietnam, the Philippines, Brunei, Indonesia, and Malaysia.

This maritime boundary, spanning decades, illustrates the malleability of geopolitical boundaries when influenced by diplomatic gestures and changing political dynamics, demonstrating the intricacies and multifaceted nature of disputes in the South China Sea.

A Glimpse of Evolving South China Sea Demarcations

The recent history of the South China Sea has seen a series of critical events and disputes among the claimant states. Let’s get back to January 19, 1974, when Chinese forces seized the Paracel Islands from South Vietnam. Subsequent confrontations include a clash between Chinese and Vietnamese naval forces in March 1988, after China’s occupation of Fiery Cross and Cuarteron reefs in the Spratlys, leading to casualties among Vietnamese sailors. The year 1994 marked a significant development when the United Nations Convention on the Law of the Sea (UNCLOS) came into effect, establishing a legal framework for maritime jurisdiction, including territorial seas, exclusive economic zones, and continental shelves. In 1995, China’s navy occupied Mischief Reef, leading to skirmishes with Philippine naval forces. The year 2002 witnessed an agreement between ASEAN member states and China on the non-binding Declaration on the Conduct of Parties in the South China Sea, with the intent to create a Code of Conduct. In May 2009, China submitted the “nine-dash line” map in response to a joint submission by Malaysia and Vietnam, raising further concerns.

The situation escalated in April 2012, when China asserted control over Scarborough Shoal, following a standoff prompted by the Philippine Navy’s attempt to arrest Chinese fishermen. The Philippines initiated an arbitration case under UNCLOS in January 2013 to challenge Chinese claims, and China commenced land reclamation and construction on several features in the Spratlys in late 2013. In May 2014, Vietnamese and Chinese vessels collided as Vietnam tried to prevent the placement of a Chinese oil rig in disputed waters. The United States started freedom of navigation operations, in the South China Sea in October 2015. A significant milestone occurred on July 12, 2016, when an arbitral tribunal in The Hague, found that China’s nine-dash line had no legal basis under UNCLOS. In July 2018, China and ASEAN agreed on a Single Draft Negotiating Text for the Code of Conduct. A notable standoff began in December 2019, involving China, Malaysia, and Vietnam over the deployment of a Malaysian drillship. More recently, in March 2021, the Philippines demanded the withdrawal of around 200 Chinese vessels, including suspected maritime militia boats, from waters around Whitsun Reef in the Spratlys.

The 2016 International Tribunal Ruling

On July 12, 2016, a significant turning point was reached in the ongoing dispute surrounding the Nine-Dash Line when an international tribunal, known as the Permanent Court of Arbitration in the Hague, issued a landmark ruling. This tribunal unequivocally declared that the Nine-Dash Line lacked any “legal basis” for making historical claims to the South China Sea—a body of water that had been claimed, in part, by six different governments. This verdict stood as a pivotal moment, emphasizing the critical importance of adhering to international law when settling territorial disputes and significantly challenging China’s maritime ambitions.

In the wake of the tribunal’s verdict, Beijing responded with a complex blend of indignation and obstinacy, vehemently challenging the tribunal’s jurisdiction and declining to acknowledge the ramifications of the judgment. China persisted in asserting its dominion over the South China Sea, especially in regions that overlapped with territorial assertions proffered by neighboring nations like the Philippines, Vietnam, and Malaysia. This sequence of events accentuated the intricate interplay between global legal norms and domestic interests in the enduring dispute pertaining to the Nine-Dash Line, a conundrum that continues to stoke regional frictions within the South China Sea.

Evolution of the 10-Dash Line

China’s publication of a new national map, featured in ‘China’s 2023 Ministry of Natural Resources map’, has once again sparked strong reactions from countries disputing its validity. The move has captured the attention of observers, sparking debates and concerns in Southeast Asia and beyond. While the appearance of the tenth dash line isn’t entirely novel, its reintegration with the original nine-dash line on the latest map holds symbolic and geopolitical implications. This development not only reaffirms China’s ambitious territorial claims, but also raises important questions about China’s regional intentions.

One of the key ramifications of this map is its impact on cross-strait relations, particularly concerning Taiwan. The inclusion of the tenth dash line on the map serves to symbolically subsume Taiwan’s territorial claims in the South China Sea, aligning Taipei more closely with Beijing’s nationalist agenda. The new map has also captured the attention of countries further south, as it denotes the dash line as a “national boundary,” using shading that extends from the nine-dashed lines within the South China Sea. This visual effect seems to project China’s territorial claims closer to the coastlines of the Philippines, Malaysia, Brunei and Vietnam. While these claims aren’t substantively altered from previous Chinese maps, the ambiguity of the dash line’s status remains concerning for neighboring nations. Amid this uncertainty, Indonesia, for example, may find its sensitivities in the South China Sea reignited as the tenth dash bisects Indonesia’s gas-rich Exclusive Economic Zone off the Natuna’s coast, potentially reopening issues that Jakarta had believed were resolved through earlier bilateral assurances.

As a result, even though the claims in the South China Sea aren’t the foremost concern for all Southeast Asian nations, China’s evolving approach continues to elicit a sense of disquiet among regional nations and global observers alike. It’s imperative to underline that maps, in and of themselves, do not carry any inherent legal authority as per the United Nations Convention on the Law of the Sea (UNCLOS). Consequently, China’s paramount challenge lies in the imperative to align its South China Sea assertions with the framework of international law. This matter has been gaining escalating global attention, particularly in light of the amplified scrutiny directed at the contested islands, coral formations, and rocky outcrops within the region.

Changing Maps and Ambiguities

China’s recent publication of a new map, known as the ’10-dash line,’ asserting territorial claims over much of the South China Sea, has escalated regional tensions and challenged the rules-based international order. This move disregards the 2016 international court ruling against China’s ‘nine-dash line’ claims and has raised concerns among ASEAN states and India. The timing, coinciding with India hosting the G20 summit, underlines China’s disregard for diplomatic resolution.

This could lead to regional security challenges and necessitate collective responses to address China’s unilateral behavior. It places China’s actions in a broader context of international diplomacy, prompting a reevaluation of diplomatic relations and a consideration of how these disputes may impact countries beyond the immediate region. This map has now made China’s intentions even more transparent, with significant consequences at regional and global realms.

Cultural and Diplomatic Entanglements

China’s “nine-dash line,” a symbol of its claims over the South China Sea, has inadvertently found its way into global popular culture, triggering political disputes and diplomatic entanglements. Recent examples include Vietnam’s ban of the film “Uncharted” due to a controversial scene featuring the nine-dash line and the Philippines’ protests against Netflix’s series “Pine Gap” for its depiction of the line, leading to the series removal from distribution setups.

While it serves to illustrate China’s South China Sea claims, the Chinese Communist Party has never explicitly defined its precise meaning, leaving international observers, legal scholars, and analysts to decipher its implications. Some see it as a maritime border, while moderate legal scholars argue for sovereignty and rights within UNCLOS boundaries. Nevertheless, concerns linger about its potential to signal Beijing’s broader territorial ambitions, including areas not subject to sovereign appropriation.

Beyond popular culture, the nine-dash line has been featured in various forms, including ESPN’s televised map and Chinese e-passports, which were declined by the Philippines and Vietnam. Its role in popular media has added to the contentious narrative of maritime territorialization, reinforcing sovereignty over maritime territories. While the contentious line remains disputed and its compatibility with international law is under scrutiny, the South China Sea conflict continues to involve complex legal challenges, diplomatic efforts, and military activities, with no resolution in sight. These ongoing tensions emphasize the multifaceted nature of the dispute, reflecting its status as a global concern, as nations strive to assert their maritime rights and address conflicting claims.

How the US Military Revive Naval Base in Subic Bay to Defend the Philippines from Chinese Invasion?

In the spring of 1975, as the Vietnam War came to a dramatic end, thousands of South Vietnamese fled their homeland, seeking safety and a new beginning. Among the chaos, Subic Bay became a sanctuary, with Grande Island serving as a temporary refuge for those escaping the fall of Saigon. For weeks, U.S. military personnel worked tirelessly to provide shelter, food, and medical care for the refugees before arranging their transfer to Guam. This pivotal moment in history exemplified Subic Bay’s capacity to address humanitarian crises while maintaining its role as a strategic military outpost.

This story is just one chapter in the rich and complex history of Subic Bay, a location that has played a significant role in shaping regional and global dynamics. During the Cold War, the Subic Bay Naval Base was a cornerstone of U.S. military strategy in Southeast Asia, protecting vital trade routes and supporting the Containment Strategy against communism. From the Vietnam War—where it served as a logistics storehouse and repair facility—to its role in humanitarian missions and post-war recovery efforts, Subic Bay proved indispensable. Its infrastructure, built to sustain aircraft carriers, submarines, and supply ships, symbolized readiness for both combat and compassion.

Yet, the closure of the base in 1992 marked a turning point, sending shockwaves through the local economy. For Olongapo City, just across the river, the end of the U.S. presence meant the loss of jobs and economic activity that had sustained the community for decades. Despite the immediate challenges, the establishment of the Subic Bay Freeport Zone heralded a new era of resilience, transforming the area into a hub for trade, tourism, and investment.

Subic Bay was more than a military installation—it was a cultural crossroads where sailors, Marines, and local residents had built connections that spanned continents and generations. The lively nightlife of Olongapo City, the legendary gatherings at Cubi Point Officers’ Club, and the enduring bonds formed at George Dewey High School all contribute to a shared history that continues to resonate. Today, remnants of this era remain alongside modern developments, offering a glimpse into the bay’s storied past and its evolving identity.

As Subic Bay steers its future, its strategic location, historical significance, and ongoing transformation make it a compelling subject for exploration. From its roots as a military stronghold to its current role as a commercial hub and its potential as a model for sustainable development, Subic Bay stands as a testament to resilience, adaptation, and the enduring connections between its past and future.

Subic Bay’s Historical Role

Subic Bay’s history as a significant maritime location date back to its recognition by Spanish conquistador Juan de Salcedo in 1542. Known for its deep and sheltered waters, the bay became an essential stop for early shipping. The name “Subic” is derived from the native term hubek, meaning “head of a plow,” reflecting the bay’s prominence in local culture. This natural harbor set the stage for Subic Bay’s future as a pivotal naval site, recognized for its unmatched geographic advantages.During the Spanish colonial period, Subic Bay gained prominence as a strategic naval base. In 1884, King Alfonso XII of Spain designated the bay as a naval port, leading to the construction of the Arsenal de Olongapo. The Spanish Gate, built in 1885, became a defining landmark of this period and remains a historic relic. Spain’s military foresight transformed Subic Bay into a critical asset for defending its Pacific territories, marking the beginning of its role in regional security. Following Spain’s defeat in the Spanish-American War of 1898, Subic Bay came under American control. Recognizing its potential, Admiral George Dewey advocated for its development as a naval facility. By 1899, the U.S. Navy officially occupied Subic Bay, establishing it as a significant outpost. Over the next decades, the Americans expanded the base, laying the groundwork for its transformation into one of the most critical military installations in the world.

Subic Bay’s importance grew during World War II, serving as a repair and supply depot for the U.S. Navy. However, it became a battleground when Japanese forces attacked in December 1941, leading to its temporary occupation. Liberated by U.S. forces in 1945, the bay’s role expanded during the post-war era with the construction of the Cubi Point Air Station by the Seabees. This engineering marvel solidified Subic Bay’s position as a cornerstone of American military logistics in the Pacific.

During the Cold War, Subic Bay emerged as the largest overseas military installation of the United States Armed Forces. Its Naval Supply Depot handled more fuel oil than any other navy facility globally, underscoring its logistical significance. The base became even more critical during the Vietnam War, supporting U.S. military operations with its Naval Air Station at Cubi Point serving as a hub for aircraft logistics. This period cemented Subic Bay’s status as a linchpin in U.S. military strategy.

Subic Bay remained a key military base until its closure in 1992, following the combined impacts of the Mount Pinatubo eruption and the Philippines’ decision to end the U.S. lease agreement. The base’s transition into the Subic Bay Freeport Zone marked a new chapter, transforming it into a thriving industrial and commercial area. Today, Subic Bay continues to play a role in regional security, occasionally hosting U.S. Navy ships, while serving as a symbol of resilience and adaptive reuse.

Closure of the US Naval Base

The closure of the U.S. Naval Base at Subic Bay in 1992 marked the end of nearly a century of American military presence in the Philippines, driven by both political and economic factors. Filipino nationalism had grown steadily over the decades, culminating in the Philippine Senate’s decision on September 13, 1991, to reject a lease extension for the base. This decision reflected a broader shift in priorities following the end of the Cold War, which reduced the strategic necessity of maintaining such a massive overseas installation. Additionally, the catastrophic eruption of Mount Pinatubo in June 1991 dealt a severe blow to Subic Bay, causing significant damage to infrastructure and forcing the evacuation of nearby Clark Air Base. Combined, these factors set the stage for the base’s eventual closure, which was finalized on November 24, 1992.

The closure had an immediate and profound impact on the local economy and community. Subic Bay had been a cornerstone of regional economic activity, employing over 5,800 military personnel, 600 civilians, and 6,000 dependents who all relocated following the base’s decommissioning. Local businesses, which had thrived on the patronage of base personnel and their families, experienced a sharp downturn, leading to widespread job losses and a significant economic contraction. The sudden withdrawal of such a substantial source of income posed a daunting challenge for the surrounding communities, leaving many grappling with uncertainty about the future.

Despite these setbacks, the region demonstrated remarkable resilience in adapting to the post-base reality. The Philippine government established the Subic Bay Freeport Zone to revitalize the area by transforming it into a hub for trade, commerce, and industry. This initiative leveraged the existing infrastructure of the former naval base, repurposing its facilities for civilian and economic uses. Over time, the Freeport Zone became a symbol of successful economic redevelopment, attracting businesses and creating new opportunities for the community. The transformation of Subic Bay underscored the potential for adaptive reuse, turning a moment of crisis into a foundation for future growth.

Economic Recovery and Development

The transformation of Subic Bay from a former U.S. Naval Base into the Subic Bay Freeport Zone (SBFZ) stands as a testament to adaptive reuse and economic resilience. Spearheaded by the Subic Bay Metropolitan Authority (SBMA), the Freeport has evolved into a dynamic economic growth center since its establishment in 1992. Leveraging the robust infrastructure inherited from the U.S. Navy, SBFZ has attracted over $2.3 billion in investments and created more than 55,000 jobs, illustrating the potential of such redevelopment efforts. Major global companies like FedEx, Acer, and Hitachi have established operations within the Freeport, enhancing its status as a hub for foreign and local investment. Even amidst challenges like the COVID-19 pandemic, SBMA reported P3.2 billion in operating revenue and secured 69 new investments in 2020, showcasing the zone’s resilience and growth potential.

Tourism has emerged as a significant pillar of Subic Bay’s post-closure economy, with efforts to promote sustainable and eco-friendly practices gaining traction. Events like the Subic Bay Tourism Summit emphasize the importance of sustainability, as highlighted by Dr. Richard Daenos of the Department of Tourism in Central Luzon, who stated, “Sustainability is everyone’s responsibility.” The impact of these initiatives is evident, with Subic Bay recording 7.3 million same-day visitors in 2021, a 42% increase from the previous year. In addition to tourism, commercial and residential development projects are transforming the region’s landscape. The Subic Bay Gateway Park (SBGP) is undergoing redevelopment into a mixed-use commercial complex, blending residential, civic, and park-like facilities with commercial spaces. This initiative aims to cater to both local and international markets, further solidifying Subic Bay’s economic significance.

Subic Bay’s post-closure evolution includes inspiring success stories and innovative developments. The Freeport has hosted sports tourism events such as the Maharlika Pilipinas Basketball League, showcasing its capability to attract diverse industries. Strict health and safety protocols have been key to maintaining the confidence of visitors and businesses alike, particularly during the pandemic. However, challenges remain, especially in aligning the Freeport’s industrial activities with environmental sustainability goals. Achieving carbon neutrality within the SBMA industrial zone is a top priority, as underscored by Amethya Dela Llana of the SBMA Regulatory Group, who urged, “Let’s make this a way of life.” The SBMA is actively pioneering carbon reduction strategies, positioning Subic Bay as a testbed for achieving widespread environmental sustainability. Balancing economic growth with ecological stewardship remains an ongoing endeavor, but Subic Bay’s progress offers a model of resilience and reinvention for similar post-military base transitions.

Personal Stories and Community Perspectives

Subic Bay’s rich history is intricately tied to the lives and memories of those who lived and worked there during its time as a U.S. naval base. For many, it was more than a military facility—it was a vibrant community and a home away from home. Former military personnel and local residents share vivid anecdotes of life around the base. Chris Reed, a young officer aboard the battleship New Jersey in 1968, fondly recalls, “It was a young sailor’s dream come true… terrific music, booze, and girls,” encapsulating the lively social scene of the era. Similarly, retired U.S. Navy officer John Hernandez described Subic Bay as a place where sailors formed lifelong friendships, stating, “Subic Bay was more than a naval base; it was a home away from home for many sailors who spent years stationed here.” At its peak, Subic Bay was bustling with activity, housing 5,800 military personnel, 600 civilians, and 6,000 dependents, creating a microcosm of American military life overseas.

The cultural and historical legacy of the base continues to resonate in Subic Bay today. Landmarks such as the Subic Bay Naval Base Museum preserve the memories of its strategic importance and the role it played in U.S.-Philippine relations. Mayor Rolen Paulino of Olongapo City reflects on this enduring impact, noting, “The closure of Subic Bay Naval Base marked the end of an era, but its impact on the local community and its role in shaping our nation’s history will never be forgotten.” Annual events and festivals celebrating U.S.-Philippine friendship highlight how deeply interwoven this legacy is with the cultural identity of the region.

In the years following the closure of the naval base, the local community has rallied around initiatives aimed at sustainable development and economic renewal. The Subic Bay Metropolitan Authority (SBMA) has spearheaded efforts to attract investments, enhance tourism, and improve infrastructure, transforming Subic Bay into a premier destination for both business and leisure. “We are committed to transforming Subic Bay into a premier destination for both business and leisure, while preserving its rich history and natural beauty,” said SBMA Chairman Wilma Eisma.

How The Philippines’ NEW STANDARD MAP Counter China’s 10-Dash Line Claim?

Recently, the Philippines has taken a decisive step to assert its territorial rights in the South China Sea by preparing to release an updated map that reflects its maritime entitlements in line with the 2016 arbitral ruling and the United Nations Convention on the Law of the Sea (UNCLOS). This new map is a clear response to China’s controversial “10-dash line” map, which claims nearly the entire South China Sea. The updated map will delineate areas such as the Kalayaan Island Group, Scarborough Shoal, Macclesfield Bank, and the Benham Rise—territories that the Philippines has long claimed as its own. Furthermore, the map will define the West Philippine Sea as the country’s 200-nautical-mile Exclusive Economic Zone (EEZ), separating it from the broader South China Sea, and thereby strengthening the Philippines’ sovereignty over these regions.

This move was prompted by the release of China’s updated “10-dash line” map in 2023, which extended China’s territorial claims even further, overlapping with the EEZs of several Southeast Asian nations, including the Philippines. The Philippine government responded swiftly, formally rejecting this new map, which contradicts the 2016 arbitral tribunal ruling that invalidated China’s sweeping claims in the South China Sea. The tribunal had affirmed that certain features in the Spratly Islands fall within the Philippine EEZ. Despite this legal victory, China continues its claims in defiance of international law, leading the Philippines to take a firm stance in defense of its sovereignty. The creation of the updated map is part of a broader diplomatic effort to assert the Philippines’ rights, and it will undergo rigorous vetting to ensure it aligns with international law and the arbitral ruling.

An intriguing aspect of the updated map is the inclusion of Sabah, a territory currently under Malaysia’s control but historically linked to the Philippines through the Sultanate of Sulu. This issue dates back to the 15th century when the Sultanate of Sulu came into possession of the region after assisting Brunei in a civil conflict. In 1878, the Sultan of Sulu leased Sabah to the British North Borneo Chartered Company, a lease that the Philippines argues never amounted to a transfer of sovereignty. After the formation of Malaysia in 1963, which included Sabah, the Philippines formally asserted its claim. Although Malaysia considers the issue settled, interpreting the 1878 agreement as a cession, the Philippines continues to lay claim to the region, albeit without actively pursuing it in recent years.

The maritime confrontation in the South China sea is part of a broader pattern of ongoing tension between China and the Philippines over sovereignty in the South China Sea. Scarborough Shoal has long been a flashpoint, and despite the 2016 arbitral ruling, China has maintained a heavy presence in the area, effectively blocking Philippine vessels from accessing this traditional fishing ground. The Philippines has responded by asserting its territorial claims more forcefully, and in recent months, it has enacted two significant pieces of maritime legislation—the Maritime Zones Act and the Archipelagic Sea Lanes Act—aimed at further strengthening its territorial integrity. In response, China has issued threats of “necessary measures” to protect its sovereignty.

The South China Sea dispute remains a complex and multifaceted issue, involving overlapping claims from multiple nations, including China, the Philippines, Malaysia, Brunei, Vietnam, and Indonesia. The region is of immense strategic importance, with vital trade routes that handle over $3 trillion in annual commerce. The United States, a longstanding ally of the Philippines, has warned China against aggressive actions, reaffirming its commitment to the Mutual Defense Treaty with the Philippines. Meanwhile, ASEAN nations find themselves caught between maintaining ties with China, an economic powerhouse, and upholding international law in the face of Beijing’s expanding maritime claims. As tensions escalate, the risk of miscalculation grows, and the future of peace and stability in the region remains uncertain. The Philippines, undeterred, is resolutely moving forward in asserting its sovereignty, with its own new map and standing firm in its diplomatic protests against China’s actions.

Historical Philippine Maps

The 1734 Velarde map, one of the earliest representations of the Philippines, offers significant historical insights into the territorial boundaries during the Spanish Empire. This map is a valuable artifact that reveals the territorial scope claimed by the Spanish colonial authorities, providing a snapshot of the Philippines during that period. The map is particularly noteworthy for its depiction of the islands, which showcases the colonial boundaries in a way that highlights the era’s geopolitical landscape. In 2024, the National Historical Commission of the Philippines (NHCP) initiated the “Landas ng Pagkabansa” (Path of Nationhood) project to honor the nation’s history. As part of this initiative, NHCP will install 43 new historical markers across Luzon, intended to commemorate key events and milestones in the journey to Philippine independence. This project is part of the broader 125th Anniversary of Philippine Independence, celebrated from 2023 to 2026.

The “Landas ng Pagkabansa” project is a pivotal effort to highlight the heroism and sacrifices of Filipinos in the fight for independence, tracing the history from the 1898 declaration of independence in Kawit, Cavite, to the end of the First Philippine Republic in 1901 in Palanan, Isabela. The 43 markers will be installed in key provinces such as Bulacan, Nueva Ecija, Tarlac, Pangasinan, La Union, Ilocos Sur, Mountain Province, and Ifugao. These markers are not only educational but also serve as reminders of the heroism and sacrifices of local communities and individuals who contributed to the independence movement. Dr. Emmanuel Calairo, NHCP chairperson, emphasized that these markers aim to remind Filipinos of the historical events that shaped their nation and the enduring spirit of their ancestors.

In parallel to this commemoration, the Philippine government is set to release a new map that will reflect the country’s territorial claims, including the West Philippine Sea and Benham Rise, which is now referred to as “Talampas ng Pilipinas.” This updated map, developed by the National Mapping and Resource Information Authority (NAMRIA), will incorporate the maritime zones and features recognized under the United Nations Convention on the Law of the Sea (UNCLOS), along with the 2016 arbitral award. According to NAMRIA Director Peter Tiangco, this map will clearly delineate areas where the Philippines has sovereignty and sovereign rights, providing legal clarity and standing up to international scrutiny. The map will also include the exact coordinates of key maritime features and will be published once the rules for the Philippine Maritime Zones Act are finalized.

The release of this updated map coincides with the ongoing tensions in the South China Sea, particularly in the West Philippine Sea, where the Philippines has faced increasing aggression from China. The Philippine government has filed multiple diplomatic protests against China’s actions, including the incidents of Chinese vessels firing of water cannons at Philippine vessels. As of December 2024, the Philippine government has filed 60 protests against China’s aggressive maritime actions this year alone, bringing the total to 193 protests since the administration of President Ferdinand Marcos Jr. These protests highlight the Philippines’ strong opposition to China’s expansive claims in the South China Sea, which are largely based on the controversial “New ten-dash line.”

The diplomatic disputes with China have intensified, with China defending its actions as necessary to protect its perceived territorial rights, particularly in the disputed areas such as Scarborough Shoal. In response, the Philippine government has repeatedly condemned these actions, emphasizing that they are illegal under international law, particularly the 1982 UNCLOS. Despite these tensions, the Philippines remains resolute in defending its sovereignty and maritime rights, using both diplomatic channels and legal instruments to assert its position in the ongoing territorial dispute.

Updated Philippine Map to Counter China’s Claims

In 2024, the National Mapping and Resource Information Authority (NAMRIA) announced plans to release a new and updated official map of the Philippines. This initiative aligns with the 2016 arbitral ruling and the United Nations Convention on the Law of the Sea (UNCLOS), aiming to assert the Philippines’ maritime entitlements and counter China’s controversial “10-dash line” claim. The updated map will reflect the provisions of the newly enacted Philippine Maritime Zones Act, which clearly defines the country’s maritime zones, including the West Philippine Sea. NAMRIA Administrator Undersecretary Peter Tiangco emphasized that this new map will align with international standards and Philippine constitutional mandates, marking a significant step forward in the nation’s defense of its sovereignty.

The updated map will accurately delineate the Philippines’ exclusive economic zone (EEZ) and continental shelf, ensuring compliance with UNCLOS and highlighting maritime boundaries with precision. This delineation is crucial for promoting environmental protection by identifying and preserving marine ecosystems and biodiversity. Additionally, the map will enhance navigation safety for both commercial and military vessels in the South China Sea by providing clear and reliable maritime charts. Administrator Tiangco noted that the previous map was based on historical agreements like the Treaty of Paris, but the new version reflects modern legal frameworks, particularly UNCLOS and national legislation.

Strategically, the updated map serves as a powerful diplomatic tool to counter China’s expansive claims over the South China Sea, now outlined in its “10-dash line” map. These claims overlap with the exclusive economic zones of the Philippines and other Southeast Asian nations, which have led to tensions in the region. By asserting its maritime rights through an internationally compliant map, the Philippines seeks to strengthen its position in upholding the 2016 arbitral ruling that invalidated China’s excessive territorial claims. Furthermore, the updated map reaffirms the Philippines’ sovereignty over the West Philippine Sea and provides a legal basis for protecting its maritime resources and enforcing territorial boundaries.

The release of the updated map is expected to garner significant international support, reinforcing the Philippines’ stance in global forums and promoting a rules-based maritime order in the Indo-Pacific region. NAMRIA is currently in the final stages of the vetting process, involving consultations with various government agencies to ensure accuracy and consistency with existing laws. While awaiting the Implementing Rules and Regulations (IRR) of the Philippine Maritime Zones Act, NAMRIA has prepared the delineation of maritime zones and archipelagic sea lanes in compliance with constitutional and international provisions.

Legal Basis and Regional Implications

The National Mapping and Resource Information Authority (NAMRIA) announced the forthcoming release of an updated Philippine map that aligns with the United Nations Convention on the Law of the Sea (UNCLOS) and the newly enacted Philippine Maritime Zones Act (Republic Act No. 12064). Signed into law by President Ferdinand Marcos Jr., this act defines the geographical extent of the country’s maritime zones, including its exclusive economic zone (EEZ) and continental shelf. The new map aims to reinforce the Philippines’ sovereign rights, particularly in disputed areas such as the Kalayaan Island Group, Scarborough Shoal, and the West Philippine Sea, while promoting compliance with international maritime standards.

The updated map is part of a broader strategy to counter China’s contentious “10-dash line” claim, which extends its territorial assertions over most of the South China Sea, overlapping with the EEZs of the Philippines and other neighboring nations. NAMRIA Administrator Peter Tiangco highlighted the “big difference” between the Philippine map, which is rooted in legal frameworks such as UNCLOS, and China’s maps, which lack international legal support. This updated map, once published, will pinpoint the Philippines’ lawful claims and strengthen its position in international discussions regarding maritime disputes.

A key focus of the new map is the promotion of sustainable maritime practices. It highlights areas of environmental importance, reaffirming the Philippines’ commitment to marine biodiversity conservation and the responsible use of marine resources. Additionally, the map provides a clear delineation of maritime boundaries, which is critical for ensuring navigation safety for commercial and military vessels operating in the South China Sea. By establishing precise territorial markers, the map enhances maritime security and supports safe passage for international shipping lanes.

Complementing this initiative, President Marcos also signed the Philippine Archipelagic Sea Lanes Act (Republic Act No. 12065), which outlines designated routes for foreign vessels and aircraft passing through Philippine waters, in accordance with UNCLOS and the Chicago Convention on International Civil Aviation. Together, these legislative measures support the Philippines’ sovereignty, protect its maritime domain, and establish a rules-based framework for managing its territorial waters.

Significance of the Map

The release of the new Philippine map will mark a historic moment, being the first update since the landmark 2016 arbitral ruling by The Hague, which invalidated China’s sweeping claims in the South China Sea. The map will highlight the Philippines’ sovereign rights and maritime entitlements recognized under international law, particularly the United Nations Convention on the Law of the Sea (UNCLOS). Anchored in the Philippine Maritime Zones Act, this legal framework clarifies the country’s maritime domain and provides a basis for asserting its rights in contested waters. Unlike China’s recently revised 10-dash line map, the Philippines’ updated map stands firmly on legal grounds, reinforcing its territorial and maritime claims through globally recognized norms.

A key feature of the updated map is the incorporation of the Philippine Rise (formerly Benham Rise), a 13-million-hectare undersea plateau located 250 kilometers east of northern Luzon. Approved by the United Nations in 2012 as part of the Philippines’ extended continental shelf, the Philippine Rise is rich in marine biodiversity, including coral reefs, algae, and sponges that sustain various fish species. Its potential goes beyond ecology, with vast deposits of methane hydrates and other valuable seabed resources such as cobalt-rich ferromanganese crusts. These minerals hold promise for the aerospace industry and global energy needs, further emphasizing the region’s strategic and economic significance.

The Philippine government has undertaken extensive scientific initiatives in the Philippine Rise, highlighted by marine expeditions like the 2017 Coordinated National Marine Scientific Research Initiatives and Related Activities (CONMIRA). Research efforts have uncovered its role as the country’s most productive tuna fishing ground and explored opportunities for renewable energy and marine biotechnology. Oceanographers are also studying currents and physical processes to better understand typhoon patterns, benefiting not just the Philippines but the entire region. Amidst maritime disputes in the West Philippine Sea, the Philippine Rise offers a secure area for continued research, illustrating the balance between scientific pursuits and national sovereignty.

The new map also integrates the West Philippine Sea, reflecting the Philippines’ ongoing efforts to counter China’s aggressive actions and reinforce its sovereign rights. President Ferdinand Marcos Jr.’s administration has prioritized these updates as part of broader maritime legislation, including the Philippine Archipelagic Sea Lanes Act. This law establishes regulated routes for foreign military and civilian vessels, ensuring compliance with UNCLOS and the Chicago Convention. By updating its map and implementing robust legal measures, the Philippines not only asserts its territorial integrity but also enhances regional stability in the face of growing tensions in the South China Sea.

Regional Tensions Over China’s New Map

In 2024, tensions surrounding China’s updated 10-dash line map remain high, with strong protests from India, the Philippines, Malaysia, Vietnam, and Taiwan. Released in August 2023, the map asserts expansive territorial claims, including disputed areas in the South China Sea and the Indian state of Arunachal Pradesh, as well as the Aksai Chin plateau. India, which considers Arunachal Pradesh its territory, was the first to issue a formal protest, with External Affairs Minister S. Jaishankar denouncing China’s claims as “absurd.” Other nations have followed suit, rejecting the map’s validity under international law. The Philippines has declared the map “illegal” and cited a 2016 Hague tribunal ruling that invalidated China’s claims. Vietnam and Malaysia have issued similar statements, emphasizing violations of their sovereignty and exclusive economic zones (EEZs). Taiwan, claimed by China as a province, has also reiterated its independent status.

China’s map introduces a tenth dash east of Taiwan, intensifying regional disputes. It reaffirms its territorial claims over nearly all of the South China Sea, encroaching on areas claimed by Brunei, Indonesia, Malaysia, the Philippines, and Vietnam. The map has also raised concerns about China’s intentions regarding Taiwan. The dispute further extends to historical contentions, such as the inclusion of Russia’s Bolshoy Ussuriysky Island, despite a 2008 treaty resolving the matter. Analysts view this move as China’s attempt to assert dominance and revive irredentist territorial ambitions.

Military maneuvers and diplomatic posturing have escalated as nations push back against China’s assertions. China’s Coast Guard has intensified patrols in contested waters, leading to confrontations with Philippine vessels and sparking fears of potential conflict. In response, countries like Malaysia and Vietnam have sought clarity and pressed for adherence to international law, particularly the United Nations Convention on the Law of the Sea (UNCLOS). These actions are compounded by the involvement of external powers like the United States, which has criticized China’s claims and pledged support for its regional allies. The Philippines and Vietnam have emphasized the importance of UNCLOS as the basis for resolving disputes and rejected China’s narrative of historical sovereignty.

Critics argue that the map’s timing reflects a calculated move by China to stir debate, ensuring its claims dominate diplomatic discussions. Analysts like James Chin of the University of Tasmania suggest that Beijing’s intent is to maintain its territorial claims at the forefront of regional politics while signaling defiance of the 2016 Hague ruling. This strategy reinforces China’s nationalist rhetoric under President Xi Jinping and highlights its willingness to assert dominance despite international criticism. However, countries like India and the Philippines have countered with public rallies, cultural events, and strong diplomatic protests, while others, such as Vietnam, prefer quieter opposition through Communist Party channels.

Despite widespread criticism, China remains resolute in enforcing its territorial claims. Beijing defends the map as a routine administrative publication, urging other nations to view it “objectively.” However, experts warn that the map risks escalating regional tensions, particularly in the South China Sea, a vital trade route with an estimated $5 trillion in annual trade passing through it. Analysts foresee heightened military encounters and closer interactions between China and U.S.-allied forces operating in the region. While countries like Malaysia, Vietnam, and the Philippines continue to voice opposition, their ability to compel China to alter its stance remains limited. The 10-dash line thus symbolizes China’s broader strategy of territorial assertion and its unyielding approach to regional disputes.

Philippines China Trade Accusations Over New South China Sea Confrontation

Tensions between China and the Philippines flared once again following a maritime confrontation near the contested Scarborough Shoal in the South China Sea, further intensifying a long-standing territorial dispute. Both nations offered conflicting accounts of the incident, highlighting the fragile state of relations in one of the world’s most strategic waterways.

The Philippine government accused China of “aggressive actions” after Chinese coast guard vessels reportedly fired water cannons and sideswiped a Philippine fisheries bureau boat that was delivering supplies to Filipino fishermen. Video evidence released by Philippine officials showed a large Chinese vessel approaching the smaller Philippine boat before the collision and the use of water cannons. Philippine Coast Guard (PCG) spokesperson Jay Tarriela labeled the actions as “overkill,” stating that they endangered lives and disrupted legitimate Philippine maritime operations.

The United States condemned China’s actions, with U.S. Ambassador to Manila MaryKay Carlson describing them as “unlawful” and reaffirming the U.S.’s commitment to supporting allies in maintaining a free and open Pacific. The U.S. has increasingly voiced concerns over China’s aggressive maneuvers in the South China Sea, with this latest confrontation drawing swift international attention.

China, however, presented a different narrative. According to the Chinese Coast Guard, four Philippine ships “dangerously approached” its vessels, attempting to enter what Beijing considers its territorial waters around Scarborough Shoal, known in China as Huangyan Island. Coast Guard spokesperson Liu Dejun defended the actions of Chinese vessels as necessary to “exercise control” over what he described as provocative and unsafe maneuvers by the Philippine side.

Liu added that one Philippine vessel ignored repeated warnings, further escalating tensions. “We warn the Philippines to immediately stop infringement, provocation, and propaganda; otherwise, it will bear all consequences,” he said in a statement.

The confrontation comes on the heels of a November diplomatic dispute after China unilaterally declared baseline territorial waters around Scarborough Shoal. This week, Beijing submitted nautical charts to the United Nations reinforcing its claims, which the Philippines has rejected as “baseless” and “illegal.” Alexander Lopez, spokesperson for the Philippines’ National Maritime Council, reiterated the country’s sovereign claim to the area, calling China’s actions part of a broader pattern of aggression, coercion, and intimidation.

“The aggressive posture of Chinese vessels highlights a continuing pattern of disregard for Philippine sovereignty and international law,” Lopez stated during a press briefing. He urged China to exercise self-restraint and respect the 2016 arbitral ruling that invalidated Beijing’s expansive claims under the United Nations Convention on the Law of the Sea (UNCLOS).

Scarborough Shoal has been a flashpoint for years. Although the arbitral tribunal ruled in 2016 that the area is a traditional fishing ground open to multiple nationalities, China has maintained a near-constant presence there, effectively blocking access to Philippine vessels. Tensions escalated further in recent months as Beijing ramped up its activities, including submitting maps that the Philippines insists infringe on its exclusive economic zone.

Philippine President Ferdinand Marcos Jr. recently signed two new maritime laws aimed at strengthening the country’s territorial integrity. The Maritime Zones Act and the Archipelagic Sea Lanes Act define the nation’s maritime zones and sea lanes more clearly, a move Beijing has called a provocation. In response, China summoned the Philippine ambassador to Beijing and warned that it would take “necessary measures” to protect its territorial sovereignty.

U S Funded Port in Batanes The Bold Move to Counter China

China claims nearly the entire South China Sea, a vital maritime route facilitating over $3 trillion in annual trade, with overlapping claims from Brunei, Indonesia, Malaysia, the Philippines, and Vietnam. Despite years of negotiations on a code of conduct for the waterway between China and the Association of Southeast Asian Nations (ASEAN), disputes persist, with some ASEAN members insisting the code must adhere to UNCLOS principles.

While Beijing asserts that its baseline submissions to the UN are consistent with international law, the Philippines and other claimants have dismissed them as lacking legal merit. “This is not a legitimate exercise of maritime rights but a blatant attempt to expand control,” Lopez said.

The ongoing dispute raises concerns about broader regional stability. The U.S.-Philippines Mutual Defense Treaty, dating back to 1951, could potentially draw Washington into any armed conflict in the South China Sea. Meanwhile, ASEAN nations continue to navigate a delicate balance between maintaining security ties with the U.S. and avoiding provocation with China, a dominant economic power in the region.

This latest confrontation highlights the growing risk of miscalculation in the South China Sea, where competing claims and aggressive posturing by China have created a volatile environment. As diplomatic efforts struggle to keep pace with the rapid escalation of maritime tensions, the future of peace and stability in the region remains uncertain.
