FBI arrests woman before China flight
The FBI has arrested a 34-year-old California woman who U.S. authorities accuse of secretly collecting information about the son of Taiwan’s president for Chinese officials.
Wanying Zhang, also known as Heather, was arrested on Sunday, October 4, at Los Angeles International Airport (LAX).
Authorities say she was arrested shortly before she was due to fly to China.
Zhang, who lives in Irvine, California, has been charged with acting as an unregistered agent of a foreign government.
U.S. authorities say she was working for Chinese officials without telling the U.S. government, as required by law.
What the FBI says she did
The FBI says Zhang was involved in watching and collecting information about Lai Ting-yu, the son of Taiwan’s President Lai Ching-te.
According to investigators, Zhang travelled to the Seattle area in 2025 after receiving instructions from Chinese officials.
Authorities say she took photographs and videos of the president’s son and his family.
She is also accused of collecting information about their vehicle license plates and sending the information to Chinese officials.
The FBI says Zhang also used methods that were meant to help her avoid being noticed.
Details of the alleged surveillance
The FBI's criminal complaint gives more details about the case.
According to reports based on the complaint, Zhang and another person travelled to the Seattle area in September 2025.
Investigators say they went to a home linked to the family of a senior Taiwanese official.
The two allegedly photographed the property.
The complaint also reportedly contains images from a neighbour's security camera. Investigators say the images show the two people appearing to record the family as they arrived home.
Authorities further allege that information about the people, their cars and their location was later sent to a Chinese government contact.
Investigators say Zhang's connection to Chinese officials began before the alleged surveillance.
According to reports based on the FBI complaint, Zhang was introduced to a Chinese government official in 2025 through a former classmate from Beijing's University of International Relations.
An FBI investigator said the university has links to China's Ministry of State Security.
These details are part of the government's case and will have to be tested in court.
Why the case is important
The case has attracted attention because the alleged target was the son of Taiwan's president.
The alleged surveillance also happened while the family was in the United States.
Photos, videos, vehicle details and information about someone's movements can be useful to people trying to track or monitor them.
However, authorities have not established in court exactly how the information was intended to be used.
Taiwan's presidential office condemned the alleged surveillance.
Taiwanese officials described the incident as an example of "transnational repression."
They also thanked the U.S. government for protecting Taiwanese citizens.
The case comes as Taiwan continues to warn about pressure and alleged intelligence activities linked to Beijing.
China and Taiwan remain at the centre of the dispute
Taiwan has its own elected government and runs itself separately from China.
China, however, claims Taiwan as part of its territory and says the island should eventually be brought under Chinese control.
Taiwan's President Lai Ching-te and his Democratic Progressive Party support Taiwan's separate political identity.
Beijing strongly opposes this position.
The dispute has made Taiwan one of the biggest sources of tension between China and the United States.
Why the United States supports Taiwan
The United States does not have formal diplomatic relations with Taiwan.
However, Washington maintains close unofficial relations with the island and provides it with defence support.
U.S. law allows Washington to help Taiwan maintain its ability to defend itself.
The arrest therefore comes during a period of high tension between the United States, China and Taiwan.
What happens next
Zhang was expected to appear in a federal court in Los Angeles on October 5.
She faces a charge of acting as an unregistered agent of a foreign government.
U.S. authorities say she did not tell the Attorney General that she was allegedly working for a foreign government.
It was not immediately clear whether Zhang had a lawyer representing her.
The charges against Zhang are allegations. Her arrest does not mean that she has been found guilty.
She remains presumed innocent unless prosecutors prove the case in court.
Why the arrest matters
The arrest highlights how seriously U.S. authorities are treating suspected foreign-government activities inside the United States.
It is also significant because the alleged surveillance involved the close family of Taiwan's president.
More information could emerge as the case moves through the U.S. courts, including details about Zhang's alleged contacts with Chinese officials and the information she is accused of collecting.
For now, the allegations remain unproven and will be decided through the U.S. legal process.
