臺灣海峽動態 — 2026年8月9日

Taiwan's 42nd Han Kuang exercise began on 5 August and runs through 14 August across all service branches, mobilising more than 20,000 reservists including two brigade-level reserve call-ups. Reporting describes officers working without the advance scripts used in previous iterations. The exercise programme includes simulated degradation of mobile-network service across a set of administrative regions, dispersal of weapons production and mobilisation of civilian factories to sustain defence manufacturing, coastal-defence and coastal-strike training, and transition of coast guard patrol vessels to wartime roles alongside naval units. The urban-resilience component is being run inside the military exercise rather than separately. The exercise was still under way at the date of this brief.

Why it matters. What is being tested is more interesting than the fact of testing. Every element listed above is a continuity problem rather than a battlefield one: whether command still functions when the script is removed, whether orders move when the network degrades, whether production continues when a facility is assumed lost, whether two maritime services under different ministries can operate as one. Those are the questions that determine whether pressure can be absorbed over time, and they are also the ones that produce evidence — Vigil's standing position is that resilience is the trackable part of deterrence precisely because programmes are either delivered or not. The observable after 14 August is what the government reports about which components were actually exercised, and what independent commentary says about them.

Chinese state media announced on 5 August that, because of the approach of Typhoon Dolphin, vessels heading north through the southern entrance of the Taiwan Strait would from the following night be subject to traffic-control measures and were to follow the instructions of maritime management authorities. Taipei called the instruction illegitimate, said Beijing has no right to restrict access to what it treats as international waters under the UN Convention on the Law of the Sea, and rejected the claim of authority rather than the safety advice. Taiwan's coast guard told operators it had observed no Chinese interference with shipping, asked vessels to report any broadcast demands, and said it would continue to safeguard freedom of navigation.

Why it matters. This belongs to the module's maritime-pressure baseline as a jurisdictional claim, not as an incident. The pattern the module tracks is the use of administrative and law-enforcement language — safety, traffic management, customs enforcement — to assert authority that a military instrument would make explicit and contestable. What makes this instance legible is that the claim was made and the practical effect was not observed: Taiwan's coast guard reported no interference. Nothing here establishes that China exercised traffic-control authority over the strait. The observable is whether such instructions recur outside weather events and whether any vessel is ever reported as complying under compulsion.
