Summary

On September 24-25, 2026, the Philippine Coast Guard attempted a resupply mission to the BRP Sierra Madre, a World War II-era ship grounded at Second Thomas Shoal (also called Ayungin Shoal or Ren'ai Jiao) in the South China Sea. The Philippines says Chinese Coast Guard and People's Liberation Army Navy vessels obstructed the mission through dangerous maneuvers that posed collision risks, forcing the mission to be suspended. The Philippines claims the area falls within its exclusive economic zone and that the resupply mission is lawful under international law and a 2016 arbitral ruling. China states the resupply mission was illegal and provocative, conducted without pre-approval, and that its vessels' actions were lawful law enforcement operations to safeguard Chinese territorial sovereignty. China accused the Philippines of violating the Declaration on the Conduct of Parties in the South China Sea. The incident broke a streak of 16 successful resupply missions completed under a 2024 provisional arrangement between the two countries.
