Taiwan has strengthened its maritime patrol capabilities around the Pratas Islands in the disputed South China Sea, deploying a new patrol boat and regularly sending larger vessels to the remote outpost as Chinese maritime activity in the area increases.
The Taiwan Coast Guard Administration said its patrol and enforcement capabilities around the Pratas Islands, also known as the Dongsha Islands, have been “comprehensively upgraded.” The move includes the formal stationing of a newly built 100-tonne-class patrol boat following completion of a wharf project in July.
According to Taiwan’s coast guard, the new vessel is intended to strengthen nearshore patrols and allow faster responses to incidents around the islands. Larger patrol vessels are also being deployed regularly, creating what Taipei describes as a multilayered maritime enforcement presence.
The Pratas Islands are located more than 400 kilometres from Taiwan, roughly between southern Taiwan and Hong Kong. Their distance from Taiwan makes them difficult to reinforce quickly and has led security experts to regard the outpost as vulnerable in the event of a serious confrontation.
The islands have no permanent civilian population but include an airstrip and are administered by Taiwan’s Coast Guard rather than its military. The area is also designated as a national park, with largely untouched coral reefs because tourism is extremely limited.
The patrol upgrade comes amid increased Chinese activity around the islands. Chinese coast guard vessels have increased their presence near Pratas, with the latest reported patrol taking place earlier in September.
Taiwan’s coast guard also said it had confiscated nine Chinese fishing boats around the Pratas Islands since the beginning of 2026. The seized vessels have subsequently been repurposed for reef patrol and marine conservation operations, according to the agency.
The development is part of a broader pattern of heightened maritime activity around Taiwan-controlled territories in the South China Sea. In June, Taiwan said two Chinese government vessels entered restricted waters around Itu Aba, also known as Taiping Island, another Taiwan-controlled South China Sea outpost. Taiwanese authorities said their patrol vessels tracked the ships and ordered them to leave the restricted area.
Taiwan’s other South China Sea holding, Itu Aba, lies in the Spratly Islands and is also claimed by China, Vietnam and the Philippines. Taiwan maintains a Coast Guard presence there, making the Pratas and Itu Aba its two principal outposts in the disputed waterway.
Taipei has increasingly relied on coast guard operations rather than direct military deployments around these disputed features. Earlier this year, Taiwan’s ocean affairs minister visited Taiping Island and observed exercises involving humanitarian assistance, medical evacuation and marine-pollution response, alongside training related to maritime enforcement. Analysts cited by Radio Free Asia described the use of coast guard forces as a way of asserting Taiwan’s position while limiting the risk of direct military escalation.
For Taiwan, the challenge is balancing maritime enforcement, environmental protection and the need to maintain its presence in isolated territory while avoiding incidents that could rapidly escalate.
The bigger question now is whether the expanded patrol presence around the Pratas Islands will remain primarily a law-enforcement measure or become part of a wider contest over control and access in the increasingly crowded South China Sea.
