Arrest at Los Angeles International Airport
Federal authorities detained Wanying “Heather” Zhang, a 34-year-old realtor from Irvine, California, as she prepared to board a flight to Shanghai. The arrest occurred on a Sunday, and she was charged with acting as an unregistered agent of a foreign government. Law-enforcement sources said Zhang and an unnamed accomplice traveled to Seattle in September 2025, rented a black Nissan Rogue, and photographed the home of Ting-Yu Lai, the son of Taiwan’s President Ching-Te Lai.
Background on Chinese Espionage Targeting Taiwan
Taiwan’s claim to independence and its pivotal role in global semiconductor production have long made it a focus of Beijing’s intelligence efforts. The People’s Republic of China (PRC) has previously been linked to operations aimed at gathering leverage over Taiwanese officials, including monitoring family members abroad.
Official Complaint Details
A criminal complaint filed by an FBI counter-intelligence squad member outlines the alleged surveillance mission. The complaint states Zhang communicated with at least two individuals she identified as working for the PRC, using the messaging app WeChat. Texts retrieved from Zhang’s iCloud account include references to “videorecording” the target and providing license-plate numbers. The affidavit notes that Zhang was introduced to a Chinese government official in June 2025 by a classmate from Beijing’s University of International Relations, an institution described as having close ties to the Ministry of State Security.
