A Chinese Type 052D guided-missile destroyer (hull number DDG-164) collided with China Coast Guard cutter CCG-3104 on 11 August while the two vessels were pursuing the Philippine Coast Guard patrol boat BRP Suluan near Scarborough Shoal. The crash, captured on video released by Manila, occurred about 10.5 nautical miles east of the disputed reef and crushed the coast-guard ship’s bow, leaving it unseaworthy. No injuries were immediately reported. According to the Philippines, three PCG ships were escorting around 35 fishing boats to deliver supplies inside the country’s exclusive economic zone when the Chinese flotilla attempted high-speed blocking manoeuvres. Philippine officials said the CCG cutter, closing from starboard, struck the destroyer after the warship abruptly crossed its path. Manila offered rescue assistance that Beijing declined. China’s coast guard said it had taken “necessary measures” to expel “intruding” Philippine vessels, and, two days later, defence-ministry spokesperson Jiang Bin blamed the incident on “dangerous manoeuvres” by the PCG. Philippine Foreign Minister Theresa Lazaro rejected the charge, insisting the collision resulted from Chinese actions. The confrontation was followed on 13 August by an aerial encounter in which a Chinese J-15 fighter intercepted a Philippine Coast Guard Cessna Caravan conducting a maritime patrol over the shoal. Manila said the fighter flew as close as 200 feet laterally and shadowed the turboprop for roughly 20 minutes, while Chinese naval ships below ordered the aircraft to “leave immediately.” The back-to-back incidents underline escalating friction around Scarborough Shoal, a rich fishing ground about 200 kilometres west of Luzon. Although a 2016 international tribunal ruling invalidated Beijing’s sweeping South China Sea claims, China maintains a constant naval and coast-guard presence at the reef. Monday’s ship-to-ship collision—the first known between Chinese vessels in the area—highlights the growing risk of miscalculation in one of the world’s busiest waterways.
