Philippines Accuses China of Cyanide Dumping in Contested Waters
The Philippines has raised serious allegations against Chinese fishermen, accusing them of systematically dumping cyanide in the waters surrounding the Spratly Islands, a highly contested area within the South China Sea. Manila characterises these actions as a deliberate act of 'sabotage', intended to eradicate local fish populations and deprive Filipino personnel stationed at Second Thomas Shoal of a vital food source.
China, however, has dismissed these accusations as 'completely unbelievable and not even worth refuting', with a foreign ministry spokesman labelling the claim a 'farce'. This latest development adds to a history of escalating tensions and confrontational incidents between the two nations in the disputed maritime region.
Allegations and Impact
According to the Philippine National Security Council (NSC), the alleged poisoning commenced last year in the vicinity of Second Thomas Shoal, where the BRP Sierra Madre, a deliberately grounded World War Two-era vessel, serves as a Philippine military outpost. NSC assistant director-general Cornelio Valencia stated that the use of cyanide not only threatens the food supply for naval personnel but also poses significant health risks through water and fish contamination, potentially damaging the coral reefs that underpin the Sierra Madre's structural integrity.
Rear Admiral Roy Vincent Trinidad, spokesman for the Philippine Navy, reported that Filipino troops had confiscated bottles of cyanide from sampan boats, allegedly launched from Chinese fishing vessels, on multiple occasions in 2023. Further incidents of alleged poisoning were observed last month, with samples subsequently testing positive for cyanide.
Regional Context and Denials
Cyanide fishing, a practice illegal under Philippine law and widely banned across Southeast Asia due to its severe ecological impact, has historically been used to stun or kill fish. The Philippines asserts it has raised these concerns with Beijing, but has yet to receive a formal response, indicating an intention to pursue a diplomatic protest. Naval and coastguard patrols have been intensified in the area.
The South China Sea is a critical global shipping route, rich in fishing grounds and believed to hold significant natural resources. It is subject to overlapping territorial claims from China, the Philippines, Vietnam, Taiwan, Malaysia, and Brunei. Beijing claims nearly the entirety of the sea, a claim rejected by a 2016 international tribunal. Tensions have notably sharpened, with recent clashes involving Chinese coastguard personnel and Philippine navy boats near Second Thomas Shoal.
