The FBI recently arrested Wanying “Heather” Zhang in California on allegations of spying on a Taiwanese government official, acting as an unregistered agent for the People’s Republic of China (PRC). Zhang, a realtor from California, was taken into custody at Los Angeles International Airport as she was about to board a flight to China. This case highlights ongoing tensions and espionage concerns between the United States and China.
Assistant Director Roman Rozhavsky from the FBI’s Counterintelligence and Espionage Division emphasized that Zhang’s arrest underscores the lengths to which the Chinese government is willing to go to further its interests. He reaffirmed the FBI’s dedication to safeguarding the sovereignty of democratic allies against transnational repression attempts by China or any foreign adversary.
According to the US Department of Justice, Zhang traveled in August 2025 from Orange County, California to the Pacific Northwest, where the Taiwanese official resides. As her flight was boarding, she allegedly informed a PRC official of her movements. Later, she was accused of going to the official’s residence and communicating detailed information about the individual and his location to the PRC, including license plate numbers of vehicles parked outside the residence. Details can be found in a report.
Under U.S. law, specifically 18 U.S.C. § 951, acting as an unregistered agent of a foreign government is punishable by fines and up to ten years in prison. This legislation has been applied in other instances involving Chinese espionage activities, such as the 2020 case of Jun Wei Yeo, a Singaporean national, who was found guilty of espionage activities, and the 2008 conviction of Tai Wang Mak, who smuggled naval intelligence into China.
Zhang’s arraignment took place in the US District Court for the Central District of California. The implications of this case resonate in a broader context of increasing scrutiny over Chinese espionage activities in the US. Zhang now faces the possibility of a significant prison sentence if convicted.
