Wanying Zhang Charged in US Over Alleged Surveillance for China

What changed

US authorities arrested Wanying Zhang, 34, of Irvine, California, at Los Angeles International Airport on October 4 as she prepared to travel to China. The FBI charged her with acting as an unregistered foreign agent and alleged that she surveilled Lai Ching-te’s son and family for Chinese officials.

The FBI said Zhang traveled to Seattle in 2025, then sent Chinese officials photos, video and license-plate information connected to the family. She is scheduled to appear in federal court in Los Angeles.

Why it matters

This case puts a personal-security allegation around Taiwan’s presidency into a US courtroom. The alleged target was identified as Lai Ting-yu, a US resident and son of Taiwan’s president. The FBI’s account describes surveillance that reached beyond a political figure to family members and identifying details such as vehicle plates.

That matters because Lai Ching-te and his Democratic Progressive Party support Taiwan’s separate identity from China, a position Beijing strongly opposes. The United States has no formal diplomatic ties with Taiwan, but remains its most important international backer and weapons supplier. A case involving the president’s family therefore sits at the intersection of domestic US law, Taiwan’s security and the wider US-China relationship.

The allegations have not been tested in court. The Chinese embassy and Taiwan’s representative office had not commented, and it was unclear whether Zhang had a defense attorney. The next concrete step is her federal court appearance in Los Angeles.
