A collision occurred near the disputed Spratly Islands in the South China Sea between a Chinese vessel and a Philippine supply ship. China’s coast guard accused the Philippine ship of entering its waters near Second Thomas Shoal in an unprofessional manner, leading to the collision. The Philippines claims the shoal falls within its exclusive economic zone based on international law, citing a 2016 arbitration ruling against China’s expansive claims. The incident underscores ongoing tensions among claimants including Vietnam, Malaysia, Brunei, and Taiwan, with potential implications for regional stability and U.S.-China relations.
