Some foreign companies are considering moving Taiwanese employees out of China after Beijing said it could impose the death penalty on “diehard” Taiwan independence separatists, said four people familiar with the matter.

The new guidelines have caused some Taiwanese expatriates and foreign multinationals operating in China to scramble to assess their legal risks and exposure, said the people, who include a lawyer and two executives with direct knowledge of the discussions.

“Several companies have come to us to assess the risks to their personnel,” said the lawyer, James Zimmerman, a Beijing-based partner at the Perkins Coie law firm. He declined to identify the companies or industries for confidentiality reasons.

“The companies are still concerned that there may be some grey areas such as whether a benign social media post or voting for a particular political party or candidate in Taiwan elections could be interpreted as engaging in pro-independence activities,” Zimmerman said.
