Taiwan wrapped up its largest annual war games, a signal of hardening defenses against a possible Chinese invasion.

• Taiwan finished its 10-day Han Kuang exercises, which began Aug. 5.
• The drills used an "unscripted" format, with real command centers reacting to changing threats for the first time.
• These are Taiwan's biggest war games since 1984, built to test readiness if China attacks.
• Defense Minister Wellington Koo told officers to fix weaknesses found during the drills.

Outlook: Taiwan will keep sharpening its defenses as tension with China stays high.
