Introduction: A Familiar Chinese Tactic in the South China Sea
When China announced its plan to create a “marine nature reserve” at the disputed Scarborough Shoal (known as Bajo de Masinloc in the Philippines), it was packaged as an eco-friendly move. But in Manila, it triggered immediate alarm bells among defense officials and veterans of the South China Sea dispute. This China Scarborough Shoal nature reserve proposal echoes past deceptions—phrases like “research facility” or “fishermen’s shelter” that once masked militarization at Mischief Reef. For the Philippines, it’s a chilling reminder: Scarborough Shoal must not become another Mischief Reef. In the escalating Philippines China conflict, vigilance is key to protecting the West Philippine Sea sovereignty.
“We Will Not Allow a Repeat of Mischief Reef”
Armed Forces of the Philippines (AFP) Chief General Romeo Brawner issued a stark warning in the South China Sea crisis:
“Once they build a structure there, that would be a different story. We are watching closely so that we will not have a repeat of Mischief Reef.”
His statement draws from painful history. In 1995, under President Fidel V. Ramos, Filipino fishermen spotted bamboo-and-steel huts on Mischief Reef—flying Chinese flags within the Philippine Exclusive Economic Zone (EEZ). Beijing called them “temporary shelters” for fishermen. Manila protested, but diplomatic vagueness prevailed.
Those “shelters” weren’t temporary. By the early 2000s, they grew into radar-equipped platforms. From 2014-2016, massive dredgers reclaimed 1,400 acres—over 500 football fields—turning the reef into an artificial island with a 3-km runway, hangars, and anti-aircraft missiles. Mischief Reef militarization made it China’s easternmost outpost, just 300 km from Palawan.
The 2016 Arbitral Ruling by the Permanent Court of Arbitration (PCA) declared Mischief Reef part of the Philippine EEZ, invalidating China’s occupation. Yet, Beijing ignored it, solidifying control without firing a shot. Today, Mischief Reef symbolizes how China South China Sea expansion erodes sovereignty through stealth.
The 2016 Victory That Never Was
In July 2016, the Philippines scored a landmark win in the 2016 Arbitral Ruling against China. Under President Benigno Aquino III, Manila challenged the nine-dash line—China’s baseless claim to 90% of the South China Sea—via UNCLOS.
The PCA ruling was resounding: It affirmed Scarborough Shoal and Mischief Reef in the Philippine continental shelf, condemned illegal island-building, and struck down the nine-dash line as invalid. Headlines blared “David Beats Goliath!”
But enforcement? Nonexistent. China dismissed the 2016 Arbitral Ruling violation, continuing operations. A People’s Daily photo of a plane landing on Mischief Reef mocked the verdict. Philippine officials knew eviction was impossible without war, opting for cautious diplomacy to avoid provoking PLA hardliners.
The 2016 Arbitral Ruling remains a moral triumph but a practical scar—proving international law needs force to matter in the Philippines China conflict.
Now, a “Nature Reserve” at Scarborough Shoal
Nearly a decade on, history rhymes at Scarborough Shoal—a vital Filipino fishing ground 120 nautical miles from Zambales. The 2012 standoff saw Chinese vessels seize control, using water cannons and blockades.
China’s Scarborough Shoal nature reserve announcement in 2025 feels like déjà vu. Officials call it a “pretext for occupation,” fearing Bajo de Masinloc occupation via “civilian” builds leading to militarization.
General Romeo Brawner warning is firm: “We have several options… but we are watching closely.” In the West Philippine Sea sovereignty fight, Philippine Coast Guard patrols and diplomatic protests aim to prevent another Mischief Reef.
The Shadow of Mischief Looms Large
Mischief Reef—300 km from Palawan, 1,100 km from China—epitomizes China South China Sea expansion. From 1995 huts to a fortified base, it ignored the 2016 Arbitral Ruling.
Regional experts labeled it a flashpoint; it proved them right. Mischief Reef militarization shows slow encroachment redraws maps silently.
Manila vows no repeat at Scarborough Shoal, where Chinese surveillance already fences off traditional fishing grounds.
A Delicate Balancing Act
The Philippines treads carefully in this South China Sea dispute 2025. Post-2016 Arbitral Ruling, Delfin Lorenzana noted China’s anger; Duterte’s “friendship” bought time but allowed gains.
Under Ferdinand Marcos Jr., strategic transparency exposes gray-zone tactics. Enhanced Defense Cooperation Agreement (EDCA) grants U.S. base access; partnerships with Japan, Australia, and Vietnam bolster deterrence. Naval upgrades like BrahMos missiles add teeth.
It’s a tightrope: Assert West Philippine Sea sovereignty without sparking war.

A Struggle Between Law and Power
Scarborough Shoal mirrors the South China Sea dispute: Might over right. Once “Panatag” (safe) for Filipino fishermen, it’s now blocked by Chinese coast guard.
The 2016 Arbitral Ruling affirmed Philippine EEZ rights, but Beijing rejected it. China’s nature reserve risks militarization, testing international law.
Manila asks: Can alliances and legality hold? Or will Scarborough Shoal join Mischief Reef as a lost monument?
The world watches—will it act, or let China South China Sea expansion prevail?
