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.

The early stages of the annual Han Kuang exercises would also focus on testing how Taiwan’s military can decentralize command in the event of a crippling communications attack.
