The Philippine Navy recovered bottles near Ayungin Shoal that tested positive for cyanide, raising concerns over alleged destructive fishing practices by Chinese vessels in the area.
The National Security Council, citing tests by the National Bureau of Investigation, warned that the toxic substance poses serious threats to marine ecosystems, Filipino troops stationed at the BRP Sierra Madre (LS 57), and local fisherfolk.
Officials said multiple bottles were seized from Chinese sampans over several months, with reports of deliberate poisoning of waters near the shoal.
Authorities stressed that the use of cyanide violates environmental laws, international maritime rules, and obligations under the United Nations Convention on the Law of the Sea.
The government vowed to take action against activities that threaten national sovereignty, marine resources, and stability in the West Philippine Sea.
