Chinese Vessel Activity Surges Near Taiwan
Taiwan has reported a sharp increase in Chinese government vessel activity around the island, raising concerns that Beijing may be testing tactics capable of disrupting vital Pacific supply routes during a future crisis.
Chinese vessel activity around Taiwan rises
Taiwan recorded 55 sightings of Chinese coast guard and research vessels around the island in June, compared with 30 in May, according to Coast Guard Administration data.
The total represented an 83% monthly increase and was 120% higher than the 25 sightings recorded in June 2025. The figures excluded activity around Taiwan-controlled islands located close to China’s coastline.
Chinese military aircraft and naval vessels already operate frequently around Taiwan. However, Taipei said Beijing was increasingly using government and coast guard ships to reinforce its territorial claims without launching conventional military operations.
Taiwan fears Pacific supply route blockade
Taiwanese officials warned that the expanded presence along the island’s eastern coast could be preparation for disrupting maritime supply routes connecting Taiwan with potential international partners.
Taipei plans to conduct live exercises involving its navy and coast guard to prepare for a possible blockade or similar escalation. These drills will focus on protecting sea routes essential for transporting energy, food and other critical supplies.
Some Chinese coast guard vessels operating in the area were reportedly converted naval destroyers. Their size, endurance and military-grade capabilities could place additional pressure on Taiwan’s smaller coast guard fleet.
China increases maritime pressure on Taiwan
Chinese coast guard ships have increasingly operated in pairs near the boundary of Taiwan’s exclusive economic zone in the Pacific. They have also broadcast questions to commercial vessels about their destinations and port movements.
Taiwan said no merchant vessel had altered course following the Chinese communications. Its coast guard instructed ships to continue normal navigation and disregard what Taipei described as unauthorised interference.
China considers Taiwan part of its territory and has not renounced the use of force to assert control. Taiwan rejects Beijing’s sovereignty claims and says only its people can determine the island’s future.
