The FBI arrested a California woman, Wanying Zhang, also known as Heather, at Los Angeles International Airport as she was preparing to leave for China. She is accused of acting as an unregistered foreign agent for China by surveilling the son of Taiwanese President Lai Ching-te, according to Reuters, Channel News Asia, and Al Jazeera.

Zhang, 34, conducted surveillance under the direction of Chinese officials, capturing photos, videos, and license plate information of her targets. Assistant U.S. Attorney Bill Essayli stated that she utilized tradecraft to avoid detection and did not inform U.S. authorities about her actions on behalf of a foreign government, as required by U.S. law, reports India Times and NPR.

The incident has been characterized by Taiwan's Presidential Office as a classic case of "transnational repression," which aims to suppress individuals associated with Taiwan's leadership. Karen Kuo, the spokesperson, strongly condemned these actions as "barbaric acts," indicating that they threaten human rights and national sovereignty, as highlighted by India Times and NPR.

Relations between Taiwan and China remain tense, particularly as China considers Taiwan part of its territory and has threatened to use force to assert its claims. Lai Ching-te and his Democratic Progressive Party maintain that Taiwan is a separate entity and do not recognize China's claims, according to multiple reports including Reuters and Channel News Asia.
