Taiwan has witnessed a surge in Chinese espionage activities. Spies in Taiwan on behalf of the CCP used a variety of channels and methods to infiltrate all sectors of the country. Chinese spies recruited Taiwanese to cooperate in developing organisations and obtaining sensitive information from the country’s government. The number of individuals in Taiwan prosecuted for Chinese espionage increased significantly in recent years, from 16 in 2021 to 64 in 2024. In February 2025, the Supreme Court of Taiwan upheld the decision of the Taiwan High Court to hand eight people, including several active-duty military officers, sentences ranging from 18 months to 13 years for collecting intelligence for China. The two officers, identified by their last names, Yeh and Su, served in the 501st and 301st battalions of the Air Defence and Missile Command of Taiwan. In January, Taiwan’s National Security Bureau (NSB) published an analysis of China’s infiltration tactics, highlighting Beijing’s attempts to use military veterans to recruit active service members. The report, ‘Analysis on the Infiltration Tactics Concerning China’s Espionage Cases,’ noted that the targets of Chinese infiltration attempts included military units, government agencies, and local associations.
