A California woman has been arrested after federal authorities accused her of acting on behalf of the Chinese government and carrying out surveillance linked to the family of Taiwan’s president.
The FBI announced the arrest of 34-year-old Wanying “Heather” Zhang on Sunday. Prosecutors have charged her with acting as an unregistered agent of a foreign government, according to a federal complaint filed in court.
Investigators allege that Zhang traveled to Seattle in 2025 to gather information about a close relative of a senior Taiwanese government official. Federal authorities later said the surveillance involved the son of Taiwan President Lai Ching-te and members of his family.
The case has drawn national attention because it involves alleged foreign influence activities on American soil and concerns tied to the long-running dispute between China and Taiwan.
According to court documents, Chinese officials directed Zhang to collect information and photographs related to the family member. Investigators claim the operation was intended to obtain details about relatives connected to Taiwan’s leadership.
The complaint states that Zhang and another individual traveled from Las Vegas to Seattle on September 1, 2025. Authorities say the pair went to the area where the relative lived and conducted surveillance activities near the residence.
Federal investigators cited security camera footage from a nearby home as part of the evidence. According to the complaint, the footage showed Zhang and the second individual waiting inside a rented black SUV outside the property.
When family members arrived at the home, investigators allege the two individuals used their phones to capture photographs or videos of the people, vehicles, and residence.
Authorities argue that such information could be valuable to a foreign government seeking details about relatives of high-ranking officials.
The complaint states that photographs of homes, vehicles, and family members could potentially be used to apply pressure or gain leverage during periods of political conflict or heightened tensions.
Federal prosecutors also allege that Zhang took steps to avoid attracting attention while carrying out the activity.
According to officials, she coordinated travel arrangements with another person and used methods intended to reduce the chances of detection.
The United States requires certain individuals who act on behalf of foreign governments to register with federal authorities. Prosecutors claim Zhang did not notify the Attorney General that she was allegedly working under the direction of foreign officials.
Failure to comply with those requirements can result in federal criminal charges.
Authorities have not released information indicating whether Zhang has obtained legal counsel. No public response from a defense attorney had been reported following the arrest.
Federal officials have also not announced charges against any additional individuals connected to the investigation.
The FBI said the case remains active and investigators continue to examine the circumstances surrounding the alleged operation.
The allegations come during a period of ongoing tension between China and Taiwan.
China considers Taiwan part of its territory and has repeatedly stated that it seeks eventual reunification. Taiwan operates as a self-governing democracy with its own elected government and institutions.
President Lai Ching-te has often been a target of criticism from Chinese officials because of his support for Taiwan’s sovereignty and self-governance.
Chinese leaders have regularly accused him of promoting separation from the mainland, while Taiwan’s government has continued to defend its democratic system and political independence.
Security experts have warned in recent years that intelligence gathering and surveillance activities involving political figures, government officials, and their relatives remain a concern in many countries.
Federal authorities allege that the information collected in this case involved sensitive personal details connected to the family of a senior political leader.
While investigators have not alleged any physical threat against the family, officials argue that gathering such information can create security risks and raise concerns about foreign influence operations.
Zhang is expected to appear in federal court in Los Angeles on Monday for her initial hearing. During that appearance, the court will address the charges and determine the next steps in the legal process.
As the case moves forward, federal prosecutors will seek to prove the allegations outlined in the complaint, while the court will evaluate the evidence presented by both sides. The investigation remains ongoing, and authorities have indicated that additional information could emerge as the proceedings continue.
