On October 24, Taiwan's Coast Guard formally accused China of deploying maritime militia vessels alongside state ships for battlefield preparation in the Western Pacific. Taiwanese defense officials assessed that these coordinated gray-zone operations serve as rehearsals for a potential maritime blockade. The deployments are increasing regional security pressure, particularly in overlapping exclusive economic zones involving Taiwan, Japan, and the Philippines.

This accusation followed an incident on October 18, when Taiwan's coast guard drove away 16 Chinese vessels operating simultaneously across four maritime zones and the Pratas Islands. The deployment utilized three distinct vessel types, including Chinese coast guard cutters, research ships, and fishing boats. Taiwanese officials condemned the incursions as hybrid warfare designed to alter the status quo and assert false jurisdiction.

How the story developed

Beginning in May 2026, Taiwan's Coast Guard tracked a surge of Chinese government vessels around the island, totaling 1,247 ships over the following months. By July, a record 244 vessels were detected in a single month, averaging nearly eight ships per day. Approximately 60 percent of the fleet consisted of China Coast Guard cutters, with the remainder being research and government boats.

The deployments were part of a gray zone strategy utilized by Beijing to assert jurisdiction without triggering armed conflict. As part of these operations, civilian research vessels mapped deep-sea trenches to gather data for anti-submarine warfare. Taiwanese officials warned that the persistent patrols could be laying the groundwork for a future maritime quarantine.

In mid-August, a suspected Chinese militia boat, identified as the Minfudingyu 07902, approached within 2.7 nautical miles of Taiwan's restricted waters. This incident highlighted the integration of civilian fishing fleets with state vessels to expand military reach into the Western Pacific.

Tensions continued into the fall. On October 1, Taiwan used water cannons against a Chinese fishing vessel near the Pratas Islands. This preceded the mass deployment of 16 vessels later in the month, which Taiwanese authorities described as a coordinated maritime harassment tactic designed to test jurisdictional boundaries.
