News broke earlier this month that the U.S. Federal Bureau of Investigation (FBI) had arrested real estate agent Wanying “Heather” Zhang for spying on Lai Ting-yu, the eldest child of Taiwanese President Lai Ching-te. Zhang lived in Irvine, California, where she worked as a real estate agent. She was originally from Changsha, China, before emigrating to the United States and naturalizing. 

Lai Ting-yu is not a political figure – members of the Lai family tend to keep a low profile. Lai Ching-te’s wife, First Lady Wu Mei-ju, does not often make public appearances with her husband. Arguably, the most famous members of the Lai family outside of Lai Ching-te himself are the family dogs, Murphy, Banban, and Luke, though Luke has since passed away. Banban in particular is best known as a dog that had lost a leg to a wild boar trap before being adopted by the Lai family.

Lai Ting-yu, who holds a doctorate in bioengineering from the University of Washington, works for electronics company Philips and lives in Seattle with his wife and son.

The FBI alleged that Lai was being surveilled by Zhang, along with other accomplices, in September 2025. It is unclear what Zhang was attempting to accomplish, given Lai Ting-yu’s lack of a political background. 

There could be a domestic political angle. Lai Ching-te has long been criticized by members of the pan-Blue camp over allegations that his son lives in the United States. The suggestion is that Lai is hypocritical in calling for Taiwan to increase defense spending to ward off Chinese threats, even as his own children live abroad. 

Alternatively, China may have sought to project its reach, or possibly to threaten Lai Ting-yu in order to have leverage over Taiwan’s president. Indeed, the idea that China might seek to kidnap the children of influential government officials in the course of an invasion, so as to blackmail political leaders during the turmoil of armed conflict, has occasionally been raised. This sort of political kidnapping is a plot thread that comes up in several episodes of “Zero Day Attack,” the hit 2025 television show dramatizing a Chinese invasion. 

Whatever the motive, according to the FBI, Zhang was working in coordination with Chinese handlers and demonstrated signs of tradecraft to cover her tracks, such as renting vehicles for several hours then returning them, or booking short-range flights with little notice. It is unclear how evidence of her activities was detected, but Zhang was arrested in October 2026 while attempting to board a flight to Shanghai. 

The FBI did not comment on when Zhang was recruited, or her motivations, seeing as she lived in a $6 million home and handled real estate transactions that were in the millions. Though there have been reports of China increasingly recruiting “disposable” agents that are used temporarily and then cast aside, tradecraft by Zhang may indicate professional training. 

The Taiwanese government has criticized such actions as Chinese transnational repression. This is not the first case occurring in the United States. Individuals allegedly working for China’s government were arrested for surveilling Taiwan’s then-President Tsai Ing-wen’s travels in California in 2023. Reports indicate that Taiwanese government officials such as Joseph Wu were surveilled during past trips to Europe. 

Most famously, news broke in June 2025 of an attempt by the Chinese military attaché in Prague to ram a vehicle into the motorcade of Taiwan’s then-vice president-elect Hsiao Bi-khim. Allegations of Chinese espionage against visiting Taiwanese government officials are fairly common; reports of China attempting direct kinetic action – what could be construed as either an attempt at intimidation or an assassination attempt – are rare. The timing of the car crash attempt raised some questions domestically in Taiwan, as this took place in a similar timeframe to the Kuomintang (KMT) introducing a bill that would require a new set of presidential elections to be held if the vice president-elect died. 

China has repeatedly sanctioned senior government officials with the Democratic Progressive Party (DPP), preventing them or their family members from doing business in China. Such sanctions have disproportionately honed in on figures involved in civil defense efforts, such as UMC founder Robert Tsao, former Sunflower Movement student leader Lin Fei-fan, or DPP legislator Puma Shen.

Shen in particular has often been targeted, He is the founder of the disinformation research organization Doublethink Lab and the civil defense organization Kuma Academy. Sanctions have honed in on his father, a businessman who sells auto parts in China. Likewise, Shen has reported threats directed at his children, as well as cases of attempted impersonation while attending conferences abroad. 

DPP senior political figures and their families likely know better than to travel to China at this point. That being said, according to the Mainland Affairs Council in June, the number of Taiwanese who have been detained in China is on the rise. While most have been detained due to fraud or criminal charges, 23 were detained for religious reasons, and one was detained on a national security charge. Past precedent shows that when Taiwanese are detained in China on national security charges, they are usually prevented from returning to Taiwan even after being released at the end of their sentences. 

China’s surveillance of the relatives of Taiwanese government officials abroad also raises the possibility of surveillance or acts of repression within Taiwan. In particular, some analysts have raised the possibility of fifth-column groups becoming active in the event of an invasion. Such groups could be constituted out of pro-China organized crime groups, such as those linked to the Bamboo Union. A number of recent espionage arrests in Taiwan in the past two years have also alleged the existence of paramilitary cells that would become active in wartime. 

That being said, it has been more common to see acts of vandalism rather than outright violence in Taiwan. An attack in late September on a comedy club in Taipei saw the club’s entrance smeared with a mixture of white paint and feces. The vandalism was carried out by a 35-year-old man surnamed Kuo, who was reportedly paid NT$50,000 by a 33-year-old man surnamed Liu for the attack. It is thought that the attack occurred because of past mockery of Chinese President Xi Jinping by one of the comedians performing at the club in a clip that went viral online. 

Nevertheless, acts of violence do occur. In July, political commentator Akio Yaita was attacked at a hotel in Taichung, where Yaita was giving a speech. The accused was a Chinese man who traveled using a Hong Kong passport. 

There have also been reports in the past month of individuals attempting to impersonate the distributors of the documentary “State Organs,” which details allegations of China conducting organ harvesting on members of the Falun Gong religious group. There have also been threats directed against screenings of “State Organs.” 

The highly partisan political environment in Taiwan is likely to stymie efforts to strengthen legal measures against transnational repression or surveillance, especially ahead of November’s local elections. In the past, the opposition KMT accused the ruling DPP of attempting a power grab when the DPP proposed the reintroduction of military courts for espionage cases.
