China rejects US involvement in South China Sea following Trump-Marcos communication

Maritime clashes between Chinese and Philippine vessels have escalated significantly, including water cannon deployment and physical collisions near Scarborough Shoal, marking a hardening of Beijing's enforcement posture. Concurrently, the Philippines is pursuing a diplomatic reset with China to de-escalate tensions, though the sustainability of this initiative is uncertain given persistent territorial disputes and China's rejection of external mediation. ASEAN and EU diplomatic efforts are underway to support a Code of Conduct, but progress remains contested.
