Taiwan has charged three men — a retired air force sergeant, a serving army sergeant major, and a retired captain — with passing military secrets to Chinese intelligence, a reminder of how deep Beijing's spying reaches inside Taiwan's armed forces.

• A retired air force sergeant allegedly took money from a Chinese intelligence group starting in late 2020.
• He is accused of using a relative still serving in the army to collect secrets on tanks, defense plans, and the Han Kuang war games — Taiwan's biggest annual military exercise.
• The group allegedly expanded in 2024, traveling to Zhuhai in China for dinners with a handler and recruiting a retired captain to approach more serving soldiers.
• Military police, local police, and the defense ministry's political warfare bureau built the case together; prosecutors wrapped it up on October 1.

Outlook: Taiwanese prosecutors say Chinese infiltration is growing and plan more joint investigations with military security units, so further spy cases are likely.
