Alleged Chinese Operative Arrested for Surveilling Taiwan President's Son

The FBI arrested a California woman on Sunday over allegations that she operated for China without notifying U.S. authorities and conducted surveillance of Taiwan President Lai Ching-te’s son and his family.

Wanying “Heather” Zhang, 34, of Irvine, faces a federal charge of acting as an unregistered foreign agent.

A complaint signed Saturday alleges Chinese officials instructed her to collect information and photographs concerning a Taiwanese official’s close relative.

The filing leaves the relative unidentified. The FBI separately named Lai’s son and his family as the surveillance targets in a social media post.

Seattle Surveillance Allegations

According to the complaint, Zhang and an associate identified as “Individual 1” traveled from Las Vegas to Seattle on September 1, 2025.

They then visited the relative’s residence.

A neighbor’s security camera recorded the pair waiting in a rented black SUV, the filing alleges. When the family returned, both appeared to raise their phones to photograph or film them.

Investigators argued that images of relatives, their residences and vehicles could give Beijing a means of pressuring Taiwan’s president during a conflict.

The complaint suggested China might use such information if it “wished to obtain leverage over the President of Taiwan during any potential conflict.”

Foreign Agent Charge

Bill Essayli, first assistant U.S. attorney for the Central District of California, alleged that Zhang arranged the trip with an associate and took steps to conceal the surveillance.

He said she had not informed the attorney general that she was working for a foreign government, the omission underlying the federal charge.

Her initial court appearance is scheduled for Monday in Los Angeles, according to CNN.

The supplied report did not establish whether Zhang had legal representation.

Taiwan Condemns Alleged Conduct

Taiwanese presidential spokesperson Karen Kuo described the allegations as “classic transnational repression.”

Beijing claims Taiwan and has not ruled out force to bring the self-governing island under its control. China’s Communist Party has never governed Taiwan.

Lai’s defense of Taiwanese sovereignty has drawn repeated attacks from Chinese officials and state media. Beijing has also rejected his offers of talks.

Washington’s longstanding “One China” policy acknowledges Beijing’s position on Taiwan without formally recognizing its sovereignty claim over the island.
