Second Thomas Shoal: Persistent Maritime Tensions

Verdict: Correct

### Topic
Second Thomas Shoal: Persistent Maritime Tensions

### Summary
Second Thomas Shoal, a low-tide elevation within the Philippines' exclusive economic zone, is a focal point of maritime conflict. The Philippines maintains a military outpost on the grounded BRP Sierra Madre, requiring regular resupply missions often challenged by China, which asserts historical claims. A 2016 international ruling rejected China's expansive claims regarding the shoal, yet confrontations persist.

### Body
Second Thomas Shoal, known as Ayungin Shoal in the Philippines, is a low-tide elevation (LTE) located within the Spratly Islands area of the South China Sea. It lies approximately 104 nautical miles from the archipelagic baseline of the Philippine island of Palawan and is situated within the Philippines' exclusive economic zone (EEZ). As an LTE wholly outside any state's territorial sea, it does not generate a territorial sea of its own and is not subject to any claim to sovereignty or appropriation by any state under international law. In 1999, the Philippines deliberately grounded the World War II-era naval vessel BRP Sierra Madre on Second Thomas Shoal to serve as a military outpost and assert its sovereignty, maintaining a small contingent of Filipino marines stationed there. The Philippines conducts regular "rotation and resupply" (RORE) missions to deliver food, water, other necessities, and rotate troops to the BRP Sierra Madre. The Permanent Court of Arbitration in The Hague, established under the UN Convention on the Law of the Sea (UNCLOS), ruled in 2016 that China's expansive claims in the South China Sea, including those based on "historic rights," have no legal basis. The tribunal specifically found that Second Thomas Shoal is an LTE within the Philippines' EEZ and that China has no entitlement to any maritime zones around the shoal.

Recent incidents underscore the ongoing tensions. On June 17, 2024, the China Coast Guard (CCG) interfered with a resupply mission by the Philippine Navy near Second Thomas Shoal. During this incident, CCG personnel allegedly boarded Philippine boats, damaged communications and navigational equipment, took seven firearms, and threw rocks at Filipino troops, resulting in eight Filipino personnel reportedly injured, with one losing a thumb. The Philippines subsequently accused China's coastguard of piracy. Prior to this, in March 2024, Chinese Coast Guard ships used water cannons against a Philippine supply vessel near Second Thomas Shoal, injuring three crew members and damaging the boat. In November 2021, the Chinese Coast Guard reportedly fired water cannons to block a Filipino resupply mission to the BRP Sierra Madre. Despite these confrontations, Beijing and Manila reportedly reached a provisional arrangement through diplomatic channels in July 2024 regarding resupply operations at the shoal, which the Philippine side described as a "Provisional Understanding." From July 2024 through March 4, 2026, the Philippines carried out 13 rotation and resupply missions without dangerous encounters, indicating a period of relative manageability, though public disagreements persist about the specifics of what was agreed upon.

China asserts historical and legal foundations for its sovereignty and maritime rights in the South China Sea, claiming activities dating back over 2,000 years. China states it was the first to discover, name, and develop the islands and adjacent waters, exercising continuous, peaceful, and effective sovereignty and jurisdiction. These claims are based on centuries of work and life by the Chinese people and administration by successive Chinese dynasties. China's Law on the Territorial Sea and the Contiguous Zone, passed in 1992, lays claim to the entire South China Sea based on these historical rights. China views the Philippines' deliberate grounding of the BRP Sierra Madre as an infringement on Chinese sovereignty and a violation of the 2002 Declaration on the Conduct of Parties in the South China Sea (DOC), which commits parties to "refraining from action of inhabiting on the presently uninhabited islands, reefs, shoals." China Coast Guard actions, such as those on June 17, 2024, are described by China as responses to Philippine vessels "dangerously approaching and deliberately colliding" with "normally navigating" Chinese vessels, asserting that multiple "stern warnings" were issued and ignored. China's Foreign Ministry spokesperson Lin Jian stated that the actions of the Chinese coast guard were "legitimate, professional and restrained" and that China would "continue to take resolute measures to safeguard its territorial sovereignty and maritime rights and interests." China has also accused the Philippines of attempting to transport construction supplies to the BRP Sierra Madre to make it a more permanent structure, which China opposes. China claims "indisputable authority over the Nanshan islands, including Ren'ai reef (Second Thomas Shoal) and its adjacent waters."

The 2016 Arbitral Tribunal ruling, which is legally binding on both China and the Philippines, explicitly declared that China's expansive maritime claims in the South China Sea, including those based on "historic rights," have no legal basis. China has rejected this ruling as "null and void" and accuses the tribunal of exceeding its authority. The Philippines Department of Foreign Affairs (DFA) maintains that resupply missions to Ayungin Shoal are legitimate activities conducted within the Philippines' exclusive economic zone (EEZ) and are in accordance with international law, particularly UNCLOS, and therefore the Philippines will not provide China prior notification for these missions. The Philippines has lodged "strongest protests" against China's actions, calling them "illegal," "aggressive," and an "illegal use of force."

### Verification
The 2016 Permanent Court of Arbitration in The Hague, established under UNCLOS, ruled that China's expansive claims in the South China Sea, including those based on "historic rights," have no legal basis concerning Second Thomas Shoal. The tribunal specifically found the shoal to be an LTE within the Philippines' EEZ, affirming that China has no entitlement to any maritime zones around it. This ruling is legally binding on both China and the Philippines.

### Supplement
China's claims to sovereignty and maritime rights in the South China Sea are based on activities asserted to date back over 2,000 years, citing its role as the first to discover, name, and develop the islands and adjacent waters. These claims are codified in China's 1992 Law on the Territorial Sea and the Contiguous Zone. China views the Philippines' grounding of the BRP Sierra Madre as a violation of the 2002 Declaration on the Conduct of Parties in the South China Sea. The international community, including the United States, the United Kingdom, Japan, Australia, other Western and Asian countries, and the European Union, has reaffirmed the 2016 arbitration ruling and rejected China's expansive claims. Concerns exist that U.S. Freedom of Navigation Operations (FONOPs), while intended to preserve international maritime law, have paradoxically undermined regional stability. The Philippines has also accused China of erecting "illegal structures" in Panganiban (Mischief) Reef in 1995, which has since become a militarized artificial island.
