The People's Republic of China conducted a large, unannounced military exercise across the western Pacific and around Taiwan in early November, according to the Institute for the Study of War and Taiwanese security officials. The operation, described by Taipei as "silent intimidation," involved more than 100 vessels and simulated cutting Taiwan off from outside intervention during a potential conflict.

The Institute for the Study of War assessed on November 6 that the PRC was conducting a major military exercise around Taiwan, with updates on November 13 confirming the operation continued for an extended period. Reuters reports Taiwan characterized the drilling as a campaign of silent intimidation designed to demonstrate China's capability to isolate the island without formally announcing war games.

Scale and Duration

Taiwan's National Security Council reported that China's military and coast guard massed more than 100 vessels in the region, conducting drills that included simulated attacks on other militaries and cities, including Taiwan's population centers. The Diplomat notes the exercise involved forces from the Eastern, Northern, and Southern Theater Commands—a level of coordination greater than the People's Liberation Army's Justice Mission 2025 exercise conducted earlier this year.

The Taipei Times reports the PLA conducted drills involving submarine-launched intercontinental ballistic missiles from waters east of Taiwan toward inland targets. With ranges extending to Hawaii and Guam, Taiwanese officials said the exercises point to Beijing's ambition to establish military dominance across the First Island Chain.

Unannounced Format

The unannounced nature of the exercise marks a shift in Chinese military signaling. Previous large-scale operations around Taiwan—including drills following then-Speaker Nancy Pelosi's 2022 visit—were publicly announced and framed as responses to specific provocations. The November exercise carried no formal announcement, no declared end date, and no stated political trigger.

ISW analysts noted the duration of the exercise and apparent efforts to sustain naval operations beyond the first island chain between Taiwan and Guam suggest the PRC aimed to test logistics and endurance for extended blockade scenarios. The silent format may serve dual purposes: demonstrating military capability while avoiding the domestic and international political commitments that come with formally announced war games.

Taiwanese Response

Taiwanese National Security Council Secretary-General Joseph Wu publicly addressed the exercises on November 6, confirming Taipei's assessment that the PRC was simulating an extended isolation of Taiwan. The announcement came after several days of elevated PLA activity that Taiwan's Ministry of National Defense had been monitoring but not initially characterizing as a unified exercise.

On November 2, Taiwan's Ministry of National Defense detected 49 PLA military aircraft sorties, including 36 operating south of Taiwan, possibly coordinating with naval deployments. Taiwanese officials told reporters the operation demonstrated China's intent to erode Taiwanese confidence in its ability to resist PRC aggression by showing it could cut air and sea access during a conflict.

The exercise coincides with ongoing U.S. efforts to bolster Taiwan's defense capabilities, though Washington has not publicly commented on the November drills. The scale and duration of the unannounced operation present a challenge for Taiwan's defense planners, who must balance public reassurance with realistic assessments of the island's vulnerability to Chinese military pressure.
