This is the best summary I could come up with:

Chinese authorities have recently announced legal changes that could impose harsh sanctions, including the death penalty, on individuals working "at separating Taiwan from China."

Taiwan's President Lai Ching-te, whom Beijing has publicly disliked and called "a dangerous separatist," reacted by saying that "China has no right to pursue cross-border prosecution of Taiwanese people."

Wu told DW that, given the broad definition of the crimes, around 90% of Taiwan’s population could potentially be criminalized — a figure Lai also reportedly shared with his party's central committee during a meeting.

Wu warned that retired members of the Taiwanese military, its government personnel, employees of sensitive high-tech companies as well as educators are all among the high-risk groups, based on new laws and previous cases.

In response to the travel alert, Beijing accused Taiwan's Lai administration of "maliciously smearing judicial documents" and issued a statement reassuring that most Taiwanese had no reason for concern and could visit China "in high spirits."

Wu Se-chih believes that the latest move is a clear attempt to "make Taiwanese people feel a certain degree of self-restraint in their speech and political expressions," hoping to replicate the suppression methods used in Hong Kong.
