Chinese Coast Guard strikes Filipino sailor at Second Thomas Shoal, raising South China Sea tensions

On 20 July 2026, a Chinese Coast Guard rigid‑hull inflatable boat carrying eight personnel approached the Philippine outpost on Second Thomas Shoal (also called Ayungin Shoal). The vessel circled the grounded warship BRP Sierra Madre, photographed the site and, according to the Philippine Armed Forces, reacted violently by striking a Filipino navy sailor on the head with a wooden baton. The sailor suffered a serious head injury and a Philippine rubber boat was damaged. Video footage released by Manila shows the encounter and the assault.

The Philippine defence ministry condemned the act as part of a “clear pattern of provocative and hostile behaviour” by China and lodged a diplomatic protest. Beijing rejected the account, saying Philippine boats ignored repeated verbal warnings, rammed a Chinese patrol boat and attacked its officers with paddles and sticks. The incident comes days before an ASEAN foreign‑ministers meeting in Manila that will be attended by Chinese and U.S. officials, including U.S. Secretary of State Marco Rubio. The clash has revived regional concerns over freedom of navigation and the enforcement of the 2016 arbitral award that affirmed Philippine rights in the disputed waters.

Both sides have exchanged accusations, and the United States has labelled China’s actions “dangerous and aggressive”. The incident underscores the fragility of peace in the South China Sea and the risk of further escalation.
