The Philippine government has formally accused China of poisoning waters near Ayungin Shoal (Second Thomas Shoal), a disputed reef in the South China Sea, according to a statement released by Manila’s Department of Foreign Affairs on Wednesday. Officials claim Chinese vessels deliberately discharged harmful substances, damaging marine ecosystems in the area where Philippine troops are stationed aboard a grounded warship.
The allegation marks a significant escalation in long-standing territorial disputes. Ayungin Shoal lies within the Philippines’ exclusive economic zone (EEZ) but is also claimed by China, which maintains a constant presence of coast guard and militia ships nearby. Analysts note this is the first time Manila has accused Beijing of chemical environmental damage in the contested waters.
‘We have credible evidence of deliberate contamination intended to force our personnel to abandon our sovereign territory,’ a senior Philippine naval officer told reporters on condition of anonymity. Satellite imagery reviewed by independent researchers appears to show unusual discoloration in waters surrounding the shoal last week.
China’s Foreign Ministry spokesperson dismissed the allegations as ‘baseless fabrication’ during a regular press briefing, insisting China has always been a responsible protector of marine environments. However, regional security experts point to China’s history of aggressive tactics in disputed areas, including reef destruction and artificial island-building.
The incident comes as ASEAN members prepare for annual talks where South China Sea disputes are expected to dominate discussions. Environmental groups warn that chemical contamination could devastate one of the world’s most biodiverse marine regions if confirmed.
