Taiwan’s Coast Guard said on November 1 that China’s Coast Guard harassed commercial shipping during its latest patrol off Taiwan’s east coast, accusing Beijing of attempting to exert what it called a “fictional jurisdiction” over the waters. Two Chinese vessels were involved in the patrol, prompting Taipei to dispatch its own ships to monitor the activity, according to a statement from Taiwan’s Coast Guard Administration.
The incident occurred as China separately sent another Coast Guard ship close to the Taiwan-controlled Pratas Islands in the South China Sea on Saturday. Taiwan regards the waters off its east coast as a critical supply corridor from allies in the event of a blockade or armed conflict, making any Chinese assertion of control over the area a sensitive flashpoint for regional shipping and security planners.
Radio Warnings to Vessels
Chinese state media released footage of one of its Coast Guard ships broadcasting a radio message claiming it was conducting law enforcement and offering assistance to vessels in the area, including an unidentified fishing trawler shown in the video. Beijing did not specify to whom the broadcast was addressed.
Taiwan’s Coast Guard rejected the characterization, stating that China’s attempts to issue radio instructions to vessels at sea represent a clear expansion of authority that violates international law and undermines regional peace and stability. Taipei maintained it holds sovereign rights and jurisdiction over its exclusive economic zone east of the island and said China has no jurisdiction over any Taiwanese waters.
Pattern Since June
China, which claims Taiwan as its own territory, has stepped up Coast Guard activity off the island’s east coast since June, conducting regular patrols that Taiwanese officials believe are rehearsals for a potential maritime blockade combining military, paramilitary and civilian assets. Taiwan rejects Beijing’s sovereignty claims over the self-governed island.
The Pratas Islands, which lie more than 400 kilometers from Taiwan and have no permanent civilian population, are considered especially vulnerable due to their isolation between southern Taiwan and Hong Kong. Taiwan’s Coast Guard has reported expelling Chinese vessels from Pratas waters multiple times so far this year, underscoring the frequency of such encounters in the contested South China Sea approach.
Strategic Shipping Lane
Taiwan’s east coast route is viewed by Taipei as a vital artery for wartime resupply from allies should the Taiwan Strait or South China Sea become impassable, giving any Chinese presence there outsized strategic weight beyond routine maritime law enforcement disputes. Analysts tracking regional tensions note the pattern fits a broader pattern of Chinese paramilitary pressure around Taiwan-administered waters.
The episode adds to a run of incidents across the Indo-Pacific in recent weeks, with Taiwan separately reporting a sharp rise in Chinese naval and official vessel activity near waters shared with Japan and the Philippines. Shipping lines and insurers monitoring Asia-Pacific risk have flagged the sustained patrol activity as a factor to watch alongside separate security pressures in the Middle East and Black Sea.
Why it matters
Taiwan’s east coast and the adjacent Pratas Islands sit astride sea lanes that Taipei considers essential to resupply in any future blockade or conflict scenario, making Chinese Coast Guard assertiveness there a direct test of freedom of navigation claims. Repeated patrols and radio warnings to commercial and fishing vessels raise the risk of miscalculation in waters used by regional and international shipping. The standoff adds another flashpoint to a year already marked by elevated maritime security incidents from the Black Sea to the Strait of Hormuz, reinforcing insurers’ and carriers’ focus on Indo-Pacific risk alongside Middle East and European conflict zones.
