The Philippines and neighbouring jurisdictions have recorded a series of maritime incidents and diplomatic protests that together underscore rising tensions in the South China Sea and the West Philippine Sea. Manila has publicly rejected Chinese jurisdictional claims, said it will keep military-to-military communications suspended, and described recent confrontations — including a medevac at Ayungin (Second Thomas) Shoal — as evidence of an escalatory “new phase.” At the same time, China has staged large-scale live-fire drills across multiple sea zones, warned Taiwan after a water-cannon clash, and defended scientific activity near Palawan that the Philippine Coast Guard says was conducted without consent. The developments complicate a looming end‑of‑2026 deadline for a South China Sea code of conduct and have prompted Manila to bolster patrols while reaffirming support for freedom of navigation.

Philippine defence ministry rejects restoring military hotlines with China

The Philippine Department of National Defense said it will not restore direct military-to-military communications with China, arguing that such channels are ineffective without mutual respect for international law and could be misused or risk escalation. The DND and Defense Secretary Gilberto Teodoro Jr. have maintained the suspension of maritime hotlines and dismissed Chinese criticism of Manila’s stance; Philippine officials indicated they will not adopt a new communications model for advance notification of maritime operations. The decision followed exchanges in which Beijing had called for direct contact to prevent miscalculation.

Ayungin medevac and publicised confrontations signal a “new phase”

President Ferdinand Marcos Jr. described a recent medevac incident at Ayungin (Second Thomas) Shoal as “distressing” and said it signalled a “new phase” in escalation in the West Philippine Sea. The Philippines and the United States condemned what they described as dangerous tactics by Chinese vessels during confrontations near the shoal. Manila’s leaders have defended publicising encounters with Chinese vessels as part of efforts to manage and deter further escalation, and officials have framed their actions as lawful defence of maritime rights.

China defends scientific research near Palawan; Philippines says no consent sought

China defended conducting scientific research near Palawan, while the Philippine Coast Guard said no consent had been sought for the activities. Chinese outlets and institutions framed the operations as normal research, and the Chinese Academy of Sciences published material related to deep‑sea research. Manila’s coast guard publicly raised objections, saying Beijing did not request Philippine consent for the work in waters near Palawan.

AFP and Manila reiterate lawful defence of maritime rights; Philippines backs global pledge

The Armed Forces of the Philippines said Manila cannot be labelled a troublemaker for standing up for its maritime rights, with AFP spokespeople stressing that defending the country’s claims in the West Philippine Sea is lawful. In parallel diplomatic moves, the Philippines joined a global pledge, initiated by the EU and other countries, reaffirming support for freedom of navigation and opposing maritime tolls.

The Philippines’ combination of diplomatic reaffirmations, public disclosures of maritime incidents, and stepped-up patrol activity underscores Manila’s strategy of both contesting expansive claims and seeking international support for navigation freedoms as incidents in the South China Sea intensify.
