Four Taiwanese soldiers have been sentenced to prison for passing sensitive information to Chinese agents, in a case that highlights the increasing levels of espionage on the island. Three of the soldiers, responsible for guarding Taiwan’s presidential office, were jailed for photographing and selling classified documents.
The case comes at a time of heightened concern over Beijing’s efforts to infiltrate Taiwan’s military and destabilise the island’s defences. Three former members of a military battalion tasked with securing the presidential building, alongside a soldier from an information warfare unit, were sentenced to prison terms of up to seven years this week.
Chung Chih-tung, an assistant research fellow at the Institute for National Defence and Security Research, commented, “The presidential office should be the most secure place, yet incidents like this still happen. This shows how severe China’s infiltration is in Taiwan.”
This latest espionage case fits into a broader pattern of intimidation by Beijing, as China seeks to undermine Taiwan’s security both militarily and psychologically, in an effort to coerce the island to submit to Communist Party rule.
According to Taiwanese prosecutors, two of the soldiers, Lai Chong-yu and Chen Wen-hao, were recruited by Chinese intelligence agents through a Taiwanese citizen named Huang Tsung-yi, who has since fled to China. Lai, a member of the 211th Military Police Battalion which guards the presidential office, and Chen, who worked in the defence ministry’s information command, took photos of classified military documents and passed them to Chinese agents. After Lai retired in 2023, two other soldiers continued to sell information to China.
The soldiers received payments of between $8,000 and $20,000 between 2022 and 2024. The Taiwanese District Court stated, “Their acts betrayed the country and endangered national security,” though the soldiers were not charged with espionage as the information was not classified as “confidential,” even though it involved internal documents from the presidential office.
Despite this, the court convicted the soldiers of corruption for accepting bribes, and Lai and Chen were additionally charged with violating Taiwan’s national security law. Their sentences ranged from five years and 10 months to seven years in prison.
Critics, including Chung Chih-tung, have argued that Taiwan’s espionage punishments are too lenient, failing to act as a sufficient deterrent. President Lai Ching-te, who has taken a stronger stance against Beijing since his election in May, has called for the return of martial law-era military courts to address spying more swiftly and severely.
“China has been taking advantage of Taiwan’s openness to recruit gangs, the media, commentators, political parties, and even active-duty and retired members of the armed forces and police to divide and subvert us from within,” President Lai said.
The latest espionage cases are part of a wider crackdown by Taiwanese authorities on military personnel suspected of spying for China. In 2023, 64 individuals were prosecuted for espionage, the majority of whom were active or retired military members. This number is a sharp rise from the 10 individuals charged in 2022.
Taiwan’s growing efforts to combat espionage come as the island faces increasing threats from Beijing, which claims Taiwan as part of China and has vowed to use force if necessary to achieve reunification. Meanwhile, Taiwan’s security relationship with the United States, its key military ally, has been called into question under President Donald Trump’s more transactional approach to foreign policy.
