Taiwan's armed forces began the Han Kuang exercises this week rehearsing a specific scenario: a Chinese naval and air blockade of the island's ports and airspace, with reservist call-ups and civilian factories drilled on wartime production continuity. The drills run alongside, not in response to, a fresh round of PLA patrols that Beijing has expanded around Taiwan's approaches. Taipei's defense ministry has not characterized the patrols as the trigger for this year's scenario design; the blockade rehearsal was set before the current patrol cycle began.

That sequencing matters. A blockade rehearsal built to a pre-existing training calendar reads as Taipei's own threat assessment, independent of this week's PLA movements, and it converges with the U.S. Nimitz carrier group's transit through disputed waters nearby, a transit Beijing has protested. Washington has not stated whether the carrier's routing was coordinated with Han Kuang's timetable. The next signal is whether Beijing's Eastern Theater Command runs its own counter-exercise before Han Kuang concludes; if it does, this becomes two militaries rehearsing the same scenario at the same time, not one side responding to the other.
