Taiwan-China Coast Guard 33-Hour Standoff at Pratas/Dongsha Islands — CCG-3501 Confronts Taiwan PCG Taichung; SCS Escalation Widens Beyond Philippines

Taiwan's Coast Guard confirmed that its patrol vessel Taichung (1,000 tons) was in a 33-hour standoff with China's CCG-3501 (5,500 tons) near the Taiwan-administered Pratas Islands (Dongsha Qundao) — with the confrontation entering its second day on May 25, 2026. The two sides exchanged radio warnings in Chinese and English asserting opposing sovereignty claims, with China's CCG-3501 having initially entered the restricted zone claimed by Taiwan on May 24. Security analysts flagged the incident as strategically significant: Pratas/Dongsha Islands are located approximately 400+ km from Taiwan proper in the northern South China Sea, making them vulnerable given their distance from Taiwan's main forces. Taiwan's NSC Secretary-General Joseph Wu linked the Pratas standoff to the broader post-Trump-Xi summit deployment of 100+ PRC vessels across the first island chain. The confrontation demonstrated that China's escalatory Coast Guard posture in the South China Sea is not confined to the Philippines-claimed West Philippine Sea features but extends to Taiwan-administered areas as well — corroborating the AFP's multi-front pressure assessment. The Pratas/Dongsha area is northwest of the Philippine Luzon Strait and Scarborough Shoal, placing it within the broader SCS competition zone that directly affects Philippine strategic interests and AUKUS Indo-Pacific deterrence planning. The CCG-3501 ultimately departed at 5 PM on May 25, ending the 33-hour standoff. No kinetic incident was reported.
