The Department of Foreign Affairs (DFA) on Wednesday, April 15, condemned as “irresponsible and unacceptable” the reported use of cyanide in Ayungin Shoal, warning of serious environmental damage and signaling a possible diplomatic response as it awaits the results of a scientific investigation.
In a statement, the DFA said it is awaiting a formal scientific report on the alleged cyanide use in Ayungin Shoal, a development that could prompt diplomatic action against those responsible.
The statement follows a recent briefing by National Security Council (NSC) Assistant Director General and spokesperson Cornelio H. Valencia, who raised concerns over the illegal discharge of toxic substances in the contested waters.
“The use of cyanide and other similar toxic agents in the marine environment is irresponsible and unacceptable, and runs counter to the obligations of States Parties under the 1982 United Nations Convention on the Law of the Sea, particularly the duty to protect and preserve the marine environment and prevent pollution at sea,” the DFA said.
Scientific findings to guide next steps
According to the DFA, authorities are still conducting scientific and technical analyses of chemicals confiscated from Chinese fisherfolk in Ayungin Shoal last year.
The DFA emphasized that the forthcoming report will serve as the basis for determining the Philippines’ next diplomatic move.
“The formal report will serve as the basis for the DFA to evaluate and determine the appropriate diplomatic action to take on this matter,” it added.
Environmental and legal violations cited
The DFA strongly condemned the use of cyanide and similar toxic agents in marine ecosystems, reiterating that such practices are “irresponsible and unacceptable.”
It warned that these actions violate international obligations under UNCLOS, particularly provisions mandating the protection and preservation of the marine environment.
Marine experts have long warned that cyanide fishing causes irreversible damage to coral reefs and marine biodiversity, posing risks not only to ecosystems but also to food security and coastal livelihoods.
Sovereignty and maritime vigilance
Reaffirming its stance, the DFA said: “The Philippines will continue to monitor and call out any infringements on its sovereignty, sovereign rights, and jurisdiction across all its maritime zones.”
Ayungin Shoal, a known flashpoint in the West Philippine Sea dispute, remains under close watch amid ongoing tensions and environmental concerns.
The government has yet to specify a timeline for the release of the scientific report, but officials indicated that all appropriate diplomatic channels remain under consideration pending the findings.
