A joint report from Washington's American Enterprise Institute and the Institute for the Study of War said Friday that Beijing may be running an undeclared far-seas exercise larger than last year's public "Justice Mission" drills, with more than 100 Chinese navy and coast guard vessels active in the western Pacific and two clusters positioned to rehearse isolating Taiwan from its outer partners.
The assessment landed twenty days before Taiwan's local elections and three weeks after National Security Council Secretary-General Joseph Wu told reporters that Chinese forces were operating at unusual scale beyond the first island chain. Taiwan's Ministry of National Defense has separately published daily counts of aircraft and ships around the island; the think-tank paper stitches those figures to open-source tracking of carrier movements.
Two concentrations on the map
According to the report, one concentration includes four task groups drawn from the PLA's eastern, northern, and southern theater commands operating between Taiwan and Guam, including the Liaoning carrier strike group that transited toward the western Pacific through the Basilan Strait in late October. A second cluster includes at least six China Coast Guard cutters plus an unspecified number of navy escorts operating close to Taiwan's periphery.
On the air side, the authors cite a ministry release from the prior week showing 49 Chinese aircraft tracked around Taiwan in a single day, including 36 sorties south of the island that may have supported the western Pacific surface groups. The paper does not claim an official announcement from Beijing; it frames the pattern as a possible silent rehearsal for blockade and isolation tactics rather than a named live-fire window.
What Taipei is weighing
For voters and planners in Taipei, the timing matters as much as the hull count. A quiet, undeclared exercise would let Beijing test logistics across three theater commands without the diplomatic cost of plastering a named drill across state media. It would also stress Taiwan's own surveillance and coast guard coordination during a campaign season when cross-strait rhetoric is already elevated.
Defense officials in Taiwan have not publicly confirmed the AEI–ISW label of an "undeclared" exercise. They have, however, kept up daily disclosures of air and maritime activity, and Wu's earlier tally of triple-digit vessels is now echoed in allied analytic writing. The report recommends treating the western Pacific clusters as a signal about supply lines to Guam and the Philippines, not only as a count of hulls circling Taiwan itself.
If the pattern holds, the next questions are whether Beijing formalizes the activity with a named announcement, and whether U.S. and Japanese assets already in the Philippine Sea adjust their sailing schedules. Until then, Taiwan's breaking read is the map: two groups, one aimed outward, one pressed inward, with election day on the calendar.
