Collision at Sea: Chinese Warship and Coast Guard Crash as South China Sea Tensions Explode

Summary
On August 11, 2025, while escorting aid shipments to fishermen near disputed Scarborough Shoal, a Chinese Coast Guard cutter (CCG 3104) collided with a Chinese Navy destroyer (PLA Navy Type 052D, Guilin) during aggressive maneuvers against the Philippine Coast Guard’s BRP Suluan. Manila released dramatic footage showing the cutter’s forecastle crumpled and BRP Suluan evading water cannon fire. The PCG offered aid to the damaged Chinese vessel, but received no response. China’s coast guard acknowledged the confrontation but denied the collision, insisting on lawful measures to protect its claims.
