TAIPEI — China may be rehearsing how to cut Taiwan off from the outside world. More than 100 People's Liberation Army (PLA) Navy and China Coast Guard vessels are spread across the western Pacific around Taiwan, and a November 6 assessment by the Institute for the Study of War (ISW), written by researcher Jackson Karas in the joint ISW–AEI China-Taiwan Update, says their positioning suggests a major exercise simulating the isolation of the island.

The deployment first became public on the evening of Tuesday, November 3, when Taiwan's National Security Council Secretary-General Joseph Wu posted tracking showing more than 100 PLA Navy and coast guard hulls in the region, two Chinese aircraft carriers at sea at the same time, and 49 PLA air sorties around Taiwan in the preceding 24 hours — the highest single-day count this year, the South China Morning Post reported on November 4.

Two rings: an outer arc toward Guam and an inner ring at the island

Karas identified two main clusters. An outer arc of four task forces drawn from three theater commands — Eastern, Northern and Southern — operates between Taiwan and Guam, anchored by the Liaoning carrier strike group, which reached the Pacific through the Basilan Strait between October 23 and 26; that positioning could deter outside military assistance in a conflict. An inner ring of at least six coast guard hulls, with navy escorts, sits directly around the island, according to the ISW–AEI update of November 6.

"The scale of these deployments suggests that the People's Liberation Army Navy (PLAN) is conducting a major exercise that simulates isolating Taiwan," Karas wrote. "The number of vessels involved and the geographic range of their deployment are greater than the PLA's most recent exercise around Taiwan — Justice Mission 2025. The coordination of surface forces from the Eastern, Northern, and Southern Theater Commands is rare." Satellite imagery cited in the assessment showed China's newest and most powerful carrier, Fujian, departing its base on Hainan, possibly heading toward southern Taiwan.

The exercise with no name — and why that matters

Unlike its recent practice, Beijing has announced nothing. "The PRC's decision to not announce a major exercise departs from recent precedent and may aim to create the impression that the PLA can isolate Taiwan at will," the assessment said, noting China normally announces and names major exercises aimed at Taiwan, as it did for the last four. ISW assessed that the movements likely serve two purposes at once: preparing for a real isolation campaign, and creating informational effects that erode Taiwanese confidence in its own defence and in the willingness of the United States and its partners to come to its aid. Presenting the deployment as routine, rather than exceptional, could also demonstrate an ability to swing rapidly from a peacetime posture to combat operations, shortening the warning time adversaries would have, the assessment said.

The air picture had been deceptively quiet before the surge. Taiwan defence ministry data put October at 232 sorties — roughly eight a day, the year's fifth-highest month — and the 2026 total at 2,264 aircraft as of November 1, after 32 sorties were registered on October 31, then the year's fourth-highest day, before the 49-sortie peak of November 2–3 and a fall back to 22 the next morning, according to the Taiwan Security Monitor figures reported by the South China Morning Post and the Taipei Times.

What is solid

  • Taiwan's National Security Council Secretary-General Joseph Wu reported more than 100 Chinese navy and coast guard vessels in the western Pacific on November 3, with 49 air sorties in 24 hours.
  • The ISW–AEI update of November 6 described two clusters — task forces between Taiwan and Guam, and coast guard and navy vessels ringing Taiwan — and said the scale exceeds the Justice Mission 2025 exercise.
  • China has announced no exercise, given it no name and set no closing date in the reports available at publication.

What is only claimed

  • That the deployment IS a blockade rehearsal is an analyst assessment (ISW), not an established fact — The Ledger Asia noted on November 9 that official observations and analyst interpretations do not establish an active blockade, and there is no evidence commercial shipping routes have been closed or an attack ordered.
  • Beijing has not commented on the assessment in the reports reviewed; the purpose of the deployment has not been confirmed by China.

What happens next is a test of signals. The posture was still holding as the assessment circulated, with no closure date announced. If Beijing names the operation, it becomes a declared political statement; if the rings quietly disperse, the episode will still have shown — which ISW says is part of the point — that a cordon of more than 100 hulls can assemble around Taiwan without warning, a name, or a single official word.
