The confrontation occurred when the Philippine Coast Guard aircraft approached the "Xiangyanghong 33" during its ecological survey near Scarborough Shoal. China's Coast Guard stated it implemented necessary monitoring and control measures to ensure the vessel's safety. The Philippines has previously accused China of conducting unauthorized research in contested areas, though recent statements focus on the aircraft's actions. China.org+2
China's Coast Guard spokesperson publicly denounced the Philippine aircraft's actions on May 7, calling them "premeditated disturbances" that threaten regional stability. The statement urged Manila to cease what it described as illegal interference in China's lawful maritime activities. No direct response from Philippine officials has been recorded since the latest escalation. China.org+1

The Philippines counters that the area falls within its exclusive economic zone under international law. This latest incident reinforces the persistent deadlock in territorial disputes between the two nations. Huanqiu+1
