Beijing, September 14, 2025 — China’s military has issued a renewed warning to the Philippines, accusing it of provocative behavior in the South China Sea just days after the Philippines conducted joint naval exercises with the United States and Japan. The warning comes as Beijing seeks to advance its controversial plan to declare parts of the disputed waters a marine nature reserve.
In a statement issued Saturday, the People’s Liberation Army (PLA) said it had conducted routine patrols in the region and was prepared to take “firm and necessary measures” if what it described as Philippine incursions into Chinese territory continue. The PLA added that “foreign interference” — an apparent reference to the U.S. and Japan — was escalating tensions and undermining regional stability.
The warning follows trilateral naval drills held last week involving the U.S., Japan, and the Philippines, aimed at strengthening maritime security and freedom of navigation. Beijing criticized the exercises as an act of “military intimidation” in an area it claims as part of its historical domain, despite international rulings that have invalidated such assertions.
Simultaneously, China is pushing forward with a proposal to designate a large section of the South China Sea as a marine protected area, a move analysts view as an attempt to reinforce its territorial claims under the guise of environmental conservation. The Philippines and other Southeast Asian nations have rejected the proposal, calling it politically motivated and legally unfounded.
With diplomatic relations increasingly strained, both Manila and Beijing continue to trade accusations over near-collisions, blocked supply missions, and aggressive patrols in contested waters. Regional observers warn that the combination of military maneuvers, ecological claims, and external alliances could further inflame one of Asia’s most volatile flashpoints.
