American citizen Thomas Weir Pauken II pleads guilty to operating as a Chinese agent

A 50-year-old expatriate faces up to a decade in prison after admitting to a years-long scheme of infiltrating U.S. circles on behalf of Beijing.

Thomas Weir Pauken II, an American who spent several years living and working in China, has entered a guilty plea in a U.S. federal court for acting as an unregistered foreign agent. The 50-year-old admitted to orchestrating a covert operation that involved gathering intelligence on American targets and attempting to infiltrate national political circles at the direction of the Chinese Ministry of State Security.

According to the Department of Justice, the activities carried out by Pauken spanned from at least 2019 through February 2026. His transition from an expatriate to a foreign operative was facilitated by his long-term residence in the country, where he developed relationships with individuals he identified as having ties to the Chinese intelligence apparatus.

A web of handlers and covert assignments

Prosecutors detailed that Pauken’s primary handler was a woman known as "Cathy," whom he met in 2017. Her instructions were varied and precise; she directed him to identify potential intelligence assets within the United States. To facilitate these meetings, Pauken reportedly provided his recruits with specialized communication devices, including laptops and cellphones, to ensure secure, encrypted contact with his handlers in Beijing.

The scope of his work went beyond a single contact. Court documents indicate he also provided reports to two other individuals, "Richard" and "William." While they claimed their interest in the information was linked to Japan, Pauken acknowledged he believed they were acting on behalf of the Chinese government. Furthermore, he was involved in selling specialized reports to a group in Wuhan that sought insights into U.S. technology and the inner workings of the Department of Justice.

National security implications

Federal authorities have characterized the operation as a significant breach of national security. Assistant Attorney General for National Security John A. Eisenberg described the conduct as a betrayal of the nation, noting that Pauken participated in a conspiracy designed to extract sensitive information from the U.S. government for the benefit of the People's Republic of China.

The FBI’s involvement in the case underscores a broader effort to counter foreign influence campaigns. Roman Rozhavsky, Assistant Director of the FBI’s Counterintelligence and Espionage Division, stated that the case demonstrates the persistent efforts of the Chinese Communist Party to undermine democratic institutions. The investigation revealed that Pauken received at least $100,000 for his services, with his handlers covering the costs of his repeated travel between China and the United States to conduct his clandestine meetings.

Pauken is currently awaiting his fate, with a sentencing hearing scheduled for September 1. He faces a maximum penalty of ten years behind bars for his role in the scheme.
