The Philippines on Friday accused Chinese vessels of obstructing a routine resupply mission to the grounded Philippine ship at Second Thomas/Ayungin Shoal, prompting condemnation from the United States and a series of Chinese military exercises and diplomatic protests. The episode has intensified tensions in the South China Sea, with Beijing staging air-sea and naval-air drills near contested features, Manila appealing to international law at the United Nations, and calls within the Philippines for further legal and defense measures.
Resupply mission to Second Thomas (Ayungin) Shoal obstructed by Chinese vessels
Philippine authorities said Chinese cutters and warships hindered or blocked a resupply mission to the grounded Philippine vessel at Second Thomas Shoal (Ayungin), marking what some U.S.-linked reporting described as the first such reported obstruction since 2024. Reports described encounters between resupply boats and Chinese maritime vessels that Philippine officials and a national task force characterized as hindrance or obstruction of the mission.
The incident drew coverage in international and regional outlets, which variously reported Chinese cutters and warships physically blocking or obstructing the Philippine mission and quoted Philippine accusations of interference. The disruption to a routine resupply run to a vessel intentionally grounded years earlier has raised concern in Manila and among its partners about freedom of navigation and operational access to maritime features claimed by multiple parties.
