A Chinese Type 052D guided-missile destroyer (hull 164) collided with China Coast Guard ship CCG 3104 on Monday while both vessels were pursuing the Philippine patrol boat BRP Suluan near Scarborough Shoal, according to video and statements released by the Philippine Coast Guard. The impact occurred about 10.5 nautical miles east of the shoal, within waters Manila considers part of its exclusive economic zone. Philippine spokesman Commodore Jay Tarriela said the coast-guard ship, after firing a water cannon at the Suluan, executed a high-speed manoeuvre that caused it to slam into the larger PLA Navy vessel. Footage shows the coast-guard ship’s forecastle crumpled; Tarriela described the damage as “substantial,” rendering the vessel unseaworthy. Philippine crews offered medical aid, but received no reply from the Chinese side. There were no immediate reports of injuries. Beijing acknowledged it had taken “necessary measures” to expel Philippine craft but did not confirm the collision. President Ferdinand Marcos Jr. told reporters Manila’s patrols would continue, vowing “we never back down” in asserting sovereign rights. The incident is the latest in a series of confrontations around Scarborough Shoal, which China seized in 2012 despite a 2016 international tribunal ruling that invalidated Beijing’s sweeping South China Sea claims.
