California woman arrested for spying on Taiwan president's son for China

The FBI arrested Wanying "Heather" Zhang, a 34-year-old California real estate agent, at Los Angeles International Airport on October 4, 2026, as she attempted to board a flight to Shanghai. Zhang is charged with acting as an unregistered agent of China for allegedly conducting surveillance on Lai Ting-yu, the U.S.-based son of Taiwanese President Lai Ching-te. Taiwan condemned the operation as "transnational repression," while China's foreign ministry dismissed the allegations as sensationalized smearing.
