China Rotates Coast Guard Task Group as Patrols East of Taiwan Intensify
China's coast guard rotated its patrol task group operating east of Taiwan on July 4, with the vessel CCGS Xiushan replacing CCGS Daishan on station, Bloomberg reported. The Daishan-led group had spent June conducting patrols, vessel inspections, fishery-protection work and rescue operations in the same waters.
Taiwan's authorities recorded 55 sightings of Chinese coast guard and research-vessel activity east of the island in June, up from 30 in May, according to figures cited by Al Jazeera on July 29. China's Maritime Safety Administration and coast guard ran several "special maritime law enforcement operations" in the area through June and July — the first time such patrols have moved into Taiwan's eastern waters in rapid succession.
A New Foothold in the Open Pacific
On June 1, a China Coast Guard formation built around a Yushan-class vessel sailed roughly 52 nautical miles southeast of Taiwan's Lanyu Island and, for the first time, asserted "law enforcement" jurisdiction in open Pacific waters beyond Taiwan's immediate coastline. By mid-July, that patrol route had become a fixture rather than a one-off, according to the Al Jazeera report.
K. Tristan Tang of the National Bureau of Asian Research said Beijing is "signalling that it wants to extend its claimed administrative jurisdiction to Taiwan's eastern waters." Ray Powell of Stanford University's Sea Light project described the pattern as a "boa constrictor strategy that intends to squeeze Taiwan one coil at a time," adding that Beijing could next target "things it needs, like LNG."
Chunhan Lin of Taipei's Institute for National Defense and Security Research said China's coast guard functions as a "second navy" that answers to the Central Military Commission. William Yang of the Crisis Group said the external environment "has fundamentally changed," arguing Washington currently lacks the "bandwidth" to respond given its focus on the Middle East.
UK, Germany and France Issue Joint Warning
The UK, Germany and France issued a joint statement in late June warning that the patrols "threaten regional stability and the freedom of navigation." US Secretary of State Marco Rubio separately said Washington disagrees with the expanded patrols, calling them destabilizing.
China's Foreign Ministry called the patrols "legitimate actions to exercise China's jurisdiction" and linked the activity to separate maritime boundary talks between Japan and the Philippines.
Part of a Wider Pattern Along the First Island Chain
The pressure east of Taiwan has coincided with friction elsewhere along the same maritime chain. Japan and China traded diplomatic protests in early July over patrols near the Senkaku/Diaoyu Islands in the East China Sea, and coast guard vessels from both countries faced off there on July 8, each accusing the other of intruding into territorial waters.
The Philippines separately reported a record 112 "dangerous" interactions between its coast guard and the China Coast Guard near Scarborough Shoal in the South China Sea in the first half of 2026. Analysts describe the combined activity — spanning the Senkakus, Taiwan's east coast, the waters off Lanyu Island and Scarborough Shoal — as a single continuous friction surface along the First Island Chain.
Background: May's Combat Readiness Patrol
The current pressure follows a "joint combat readiness patrol" that Taiwan's defense ministry reported in late May, shortly after a summit between US President Donald Trump and Chinese President Xi Jinping in Beijing at which Taiwan was discussed. Taiwan detected 29 Chinese aircraft, including fighter jets, and seven warships operating around the island, with 24 of the 29 aerial sorties crossing the Taiwan Strait median line.
Officials said China had deployed more than 100 ships along the First Island Chain in the days before that patrol, and Taiwan also reported sighting the Liaoning carrier group in the West Pacific. Taiwan's National Security Council secretary-general, Joseph Wu, called the patrol "unprovoked" in a social media post at the time.
