TAIPEI (Taiwan News) — Prosecutors have charged two individuals under Taiwan’s National Security Act for allegedly providing military information to a Chinese agent.

A former private, surnamed Lin (林), and an active-duty member of the Navy’s Haifeng missile force, surnamed Tsai (蔡), are accused of sharing training and operating materials for the Hsiung Feng II missile system with a Chinese intelligence officer in Shanxi, per UDN.

Shortly after enlisting, Lin was reportedly dismissed from the Navy for gambling and later became involved with a Chinese intelligence agent posing as a reporter in Hong Kong. The agent, using the name Chu Ting (楚亭), met Lin via a dating app in January 2023 and persuaded him to solicit material from former colleagues, prosecutors said. Lin then convinced Tsai to provide information to Chu.

Tsai reportedly completed a questionnaire for the agent in exchange for NT$8,000 (US$260). After the initial payment, Tsai used a smartphone to copy two documents and send them to Chu for an additional NT$30,000 (US$975).

The two documents were a deployment drill manual and an operating manual for the Hsiung Feng II missile launcher platform. The Navy said the material was not classified, but transferring it to a Chinese agent still harmed national security and troop morale.

Lin and Tsai have been charged under the National Security Act, with Tsai also facing charges of accepting bribes and dereliction of duty.
