Amped-up drills and new U.S. tanks have added bite to President Lai Ching-te’s Taiwan-is-a-country lecture tour.

Much like Ukraine’s unexpectedly resilient defence, Taipei wants Beijing to understand that a military conflict would not be as easy, or predictable, as once thought.

Taiwan's annual military exercise, Han Kuang, begins on Wednesday as the island ramps up its defence against a possible invasion from China. Billed as the largest and longest one so far, this year's Han Kuang will last for about 10 days, about twice the duration of last year's drill.
