Chinese Militia Boat Spotted Off Taiwan’s East Coast for First Time

A Chinese fishing vessel identified as part of Beijing’s maritime militia has been detected operating off Taiwan’s eastern coast alongside a Chinese coast guard cutter and a research ship, marking the first known public sighting of a Chinese maritime militia vessel in the strategically sensitive waters east of the island.

The vessel, identified as Minfudingyu 07902, was detected in mid-August more than 30 nautical miles off Hualien County, according to a surveillance report produced by Taiwan-based Apex Aviation and reviewed by Reuters. The vessel was observed in the same area as Chinese Coast Guard ship 2502 and the research vessel Xiang Yang Hong 03.

Taiwanese officials confirmed that the three vessels had been operating near the island at the time. One official said authorities had identified the fishing boat as belonging to China’s maritime militia fleet and were tracking its movements in connection with Chinese coast guard activity. Another official said the vessels were operating in an area not commonly used by Chinese ships and had therefore been placed under heightened monitoring.

Taiwan’s Defence Ministry said China was using law-enforcement and scientific-research activities as cover to expand its maritime operations during peacetime and create what Taipei described as an appearance of de facto jurisdiction. The ministry said Taiwan’s armed forces were using surveillance and reconnaissance capabilities in coordination with the coast guard to monitor the activity.

Taiwan’s Coast Guard Administration separately said on Thursday that Chinese vessels around the island are monitored around the clock and that the ships involved in the latest report were operating outside Taiwan’s restricted waters. That means the reported activity did not constitute an entry into Taiwan’s 12-to-24-nautical-mile restricted zone.

The location nevertheless matters strategically. Taiwan’s eastern coastline faces the open Pacific rather than the Taiwan Strait, and Taipei regards the waters as important to potential external supply and reinforcement routes in the event of a conflict or maritime blockade. Chinese coast guard activity in the area has increased since June, adding to concerns in Taiwan that Beijing is broadening the geographical scope of its maritime pressure.

The reported involvement of a maritime militia vessel is particularly significant because such boats occupy an ambiguous space between civilian fishing and state-backed security operations. China has used maritime militia forces for decades, with fishing vessels and their crews receiving training or support that can allow them to operate alongside government maritime forces. The approach can give Beijing a means of maintaining pressure without relying exclusively on conventional naval ships.

At the same time, the available evidence does not establish precisely what the three vessels were doing together. Apex Aviation said its surveillance aircraft detected the vessels spread across an area of roughly 10 nautical miles. Its report used radar, infrared imagery and automatic identification system data, but the company acknowledged that a single surveillance operation could not determine the vessels’ missions or prove that they were coordinating.

Apex said the surveillance was conducted independently rather than on behalf of the Taiwanese government. The company operates a civilian aircraft equipped with U.S.-made radar capable of detecting relatively small surface objects, reflecting Taiwan’s wider effort to involve civilian capabilities in monitoring activities around the island.

The latest sighting follows a broader increase in Chinese maritime activity around Taiwan. Taiwan reported that 244 Chinese coast guard, research and other vessels were detected around the island in July, a sharp increase from the numbers recorded in May and June. Separately, Taiwan’s coast guard has intercepted or monitored Chinese research and coast guard vessels in waters around the island in recent months.

Beijing considers Taiwan part of China and has not renounced the use of force to assert control over the island, while Taiwan’s government rejects Beijing’s sovereignty claims. China’s Taiwan Affairs Office and Defence Ministry did not respond to Reuters’ requests for comment on the August militia-vessel sighting.

For Taiwan, the significance of the incident is therefore less about one fishing boat and more about the possibility of a changing pattern. The appearance of a militia-linked vessel alongside Chinese coast guard and research assets in waters where such activity has been less common could make it harder for Taipei to distinguish ordinary maritime activity from coordinated grey-zone pressure. It also highlights how competition around Taiwan is increasingly extending beyond fighter jets and warships into the use of civilian-looking vessels, law-enforcement patrols and research platforms.

The broader concern is that sustained activity of this kind can gradually normalize a Chinese presence around Taiwan without crossing the threshold of open conflict. Whether the August sighting represents a deliberate expansion of China’s maritime strategy or an isolated operation remains unclear, but Taiwan’s decision to place the vessels under heightened surveillance shows that even activity well outside its restricted waters is now being treated as part of a wider security challenge.
