Taiwan and China Coast Guards Clash Near Pratas Islands

On 5 June 2026 the Chinese Coast Guard patrol ship 3501 entered the 24-nautical-mile restricted zone around the Taiwan-administered Pratas (Dongsha) Islands, ignoring radio warnings from Taiwan’s patrol boat Hsun Hu No. 9. The next day a Chinese survey vessel, Hai Si Lu No. 6, joined it, marking the first coordinated coast-guard-survey operation aimed at “provoking” Taiwan. Taiwan dispatched frigate CG-129 Kaohsiung, two patrol boats and additional coast-guard units; the two sides exchanged radio messages for over 30 hours before 3501 withdrew.

The Pratas atoll lies about 250 miles southwest of Taiwan and 200 miles east of Hong Kong. Both the People’s Republic of China and Taiwan claim it, but Taiwan administers the islands and maintains a small coast-guard garrison. Chinese vessels have stepped up activity: research ship Tong Ji Hao operated near Taiwan in early May, and the Coast Guard reports over 30 incidents annually around Pratas, up from occasional transits. The June encounter is the first coordinated coast-guard-survey action.

Taiwan’s Coast Guard Administration (CGA) said the Chinese vessels attempted to create a false impression of jurisdiction, violating international law and asserting that only Taiwan can enforce maritime rules around Pratas. The CGA warned the actions undermine peace in the Taiwan Strait. The Chinese Taiwan Affairs Office declined comment; its coast-guard broadcasts described the operation as a law-enforcement mission and asserted that Taiwan would eventually be reunified with the mainland.

National Security Council Secretary-General Joseph Wu called the Chinese moves “highly provocative” and labeled the PRC a “sick bully” causing trouble. Defense analyst Bryce Barros of the Institute for National Defense and Security Research suggested the incidents may be part of Beijing’s “salami-slice” strategy to test resolve in Taipei, Washington and allied capitals. Gray-zone analysts view the pattern as coercive pressure below the threshold of armed conflict.

• “The China Coast Guard’s harassment of restricted Pratas is aimed at creating an illusion that China has jurisdiction over the waters around the Pratas Islands,” — Taiwan Coast Guard Administration

The incident underscores rising maritime tension in the South China Sea, challenges Taiwan’s de-facto sovereignty and raises the risk of miscalculation between civilian law-enforcement vessels and military forces. It also illustrates Beijing’s use of gray-zone tactics to assert claims without crossing the threshold of open warfare.

Taiwan plans to boost coast-guard surveillance and reconnaissance around its outlying islands while monitoring further Chinese maritime activity. International observers are watching for any escalation that could draw in regional powers.
