Taiwan's annual military drills reach peak

China has been ramping up its military pressure against the island it claims as "sacred" Chinese territory, hoping to force the democratically elected government to accept Beijing's sovereignty, including with repeated exercises near Taiwan.

Tsai, re-elected by a landslide last year on a pledge to stand up to China, has made modernizing Taiwan's mainly U.S.-equipped military a priority, turning it into a "porcupine," both highly mobile and hard to attack.
