A Taiwan court has convicted a former presidential aide of spying for China and three others who were also employed by the ruling Democratic Progressive Party (DPP). One of the men worked in the office of then Foreign Minister Joseph Wu who now serves as the national security chief. The court handed the men jail terms of between four to ten years for leaking state secrets. The ruling stated that the espionage was conducted over a lengthy period and involved the sharing of significant diplomatic intelligence.

Beijing has long claimed Taiwan as part of its territory, resulting in decades of mutual surveillance between the two. However, Taiwan asserts that Chinese spying activities have surged in recent years. Of the four men sentenced, Huang Chu-jung, a former assistant to a Taipei councilor, received the longest sentence of ten years, while prosecutors initially sought sentences of up to 18 years.

Huang directed a foreign office staffer to obtain sensitive information from Wu, then composed reports to transmit to Chinese intelligence. This included details about the travels of current President Lai Ching-te. The court reported that Huang received almost NT$5 million ($163,172) from the Chinese government.

This conviction is part of Taiwan's expanded efforts to combat Chinese espionage, with 64 people prosecuted for spying activities in 2024 alone, a significant increase compared to previous years. Espionage charges have also targeted high-ranking officials in the military and government. As Taiwan's political landscape becomes increasingly polarized, debates continue regarding its approach to relations with China, particularly under President Lai, characterized as opposed to Chinese influence.
