Taiwan is intensifying its crackdown on individuals holding illegal Chinese identity documents, revoking the citizenship of over 20 people and scrutinizing tens of thousands of Chinese-born residents. This campaign has sparked controversy, particularly following the expulsion of three women accused of supporting a Chinese takeover, raising concerns about free speech and national security. As tensions with China escalate, Taiwan’s government is implementing measures to distinguish identities on both sides of the Taiwan Strait, emphasizing the importance of national security.
