FBI arrests Chinese agent for spying on Taiwanese president's family

A black Nissan parked near a house on the outskirts of Seattle. Inside, a real estate agent and a companion. Outside, an engineer returning home to his wife and son. The scene, reconstructed by the FBI, looks like a routine surveillance until the last name of the man they were recording appears: Lai.

His father is the president of Taiwan. According to the American investigation, the images of that family ended up in the hands of Chinese officials.

Zhang Wanying, known as Heather, 34, a resident of Irvine, California's Orange County, was detained on Sunday at Los Angeles International Airport when she was about to board a flight to Shanghai. She is formally accused of "acting as an agent of a foreign government without required notification to US authorities." The complaint points to an operation against the intimate environment of the Taiwanese leader Lai Ching-te, whom Beijing considers a separatist.

The main target was his son, Lai Ting-yu. This engineer works for Philips and lives near Seattle with his wife and young son, born in the United States. The complaint initially identified the person under surveillance as a relative of a high-ranking Taiwanese official. The FBI confirmed a few hours ago that the operation affected the president's son and his family.

The follow-up would have occurred on September 1, 2025. Zhang and a man whom the file identifies only as "Individual 1" flew from Las Vegas to Seattle, rented a black Nissan Rogue and drove to the home. A neighbor's security camera captured the two when, according to investigators, they appeared to be recording the arrival of the engineer, his wife and the child. CBS contrasted the images with a property owned by Lai's son.

"I saw him. A young man. He is that young man," Zhang reportedly wrote to his Chinese contact. Then he added: "I'm recording video," and sent two license plates. Messages from WeChat, China's equivalent of WhatsApp, are a centerpiece of the indictment. The FBI claims that it obtained them through a search warrant for his iCloud account and that they show contacts with at least two people whom Zhang seemed to recognize as officials of the People's Republic.

The assignment had been prepared months before, according to the affidavit of FBI agent Kevin Holt. In June 2025, a former classmate at the Beijing University of International Relations reportedly introduced Zhang to a Chinese official. Holt links that institution to the Ministry of State Security, the Chinese civilian intelligence service. During that trip, the agent reserved a private room in Changsha, where she allegedly received the mission.

"I can take care of this," he wrote later, according to the complaint. On August 26, she announced that work in Los Angeles would keep her busy that week and that she would probably travel to Seattle the following week. His interlocutor responded by thanking him for his effort.

Why would Beijing want those images? Holt raises a hypothesis: knowing the location of the president's relatives, their homes and their vehicles could provide China with leverage during a possible conflict.

The complaint does not prove a kidnapping or assault plan. It describes the collection of information that, in the researcher's opinion, could be used against a political leader through his or her family.

Taiwanese authorities on Monday described the episode as "transnational repression" and thanked Washington for protecting its citizens. Zhang is scheduled to make his first court appearance this Monday in Los Angeles.

Spy networks in Taiwan

The shadow of Chinese espionage has reached the doors of power in Taipei on several occasions. In March 2025, a court convicted four soldiers of selling secrets to China; three had served in the unit in charge of protecting the presidential building. They received sentences of up to seven years. According to the prosecution, they photographed classified documents and charged for their sensitivity and for recruiting colleagues.

Another investigation penetrated the Democratic Progressive Party, Lai's ruling party. Former employee Huang Chu-jung was sentenced last July to 10 years for developing a network for China aimed at obtaining classified information, including travel details of the then vice president. It was a separate cause from the leak of secrets for which his sentence had been reduced to six years in June. In that procedure, two other defendants had their sentences reduced and a fourth was acquitted.

According to the latest available data, the Taiwanese National Security Office counted 64 people prosecuted for alleged Chinese espionage in 2024, compared to 48 in 2023 and 10 in 2022. Its report describes recruitment through debt, money, personal relationships and front companies, with active and retired military among the main targets. Taipei maintains that these networks seek both to steal secrets and to prepare actions that would facilitate an eventual Chinese offensive.

Beijing claims the autonomously governed island and keeps the option of taking it by force open. The pressure can also advance away from surrounding ships and fighters. The US investigation now points to a front that crosses the Pacific and reaches a family home. In the FBI file, the strategic data is a license plate; the possible instrument of pressure, the president's son.
