China wary of Taiwan firms' pro-independence link

China's government has warned Taiwanese businesses operating in the mainland against siding with pro-independence forces in Taiwan.

China's Taiwan Affairs Office spokesperson Zhu Fenglian issued the warning in a statement released on Monday.

The move came after the state-run Xinhua news agency reported that firms operated by Taiwan's Far Eastern Group were punished by local authorities in places like Shanghai and Jiangsu for a range of alleged illegal activities.

Zhu didn't explicitly state whether Far Eastern Group was linked to Taiwan's independence forces.

But Zhu said that while Beijing welcomes Taiwanese firms prospering in mainland China, it will never allow backers of Taiwan's independence to earn money on the mainland.

Zhu warned that Taiwanese businesses should draw a clear line between themselves and supporters of independence for Taiwan.

Beijing has been ramping up pressure on Taiwanese President Tsai Ing-wen's administration. Earlier this month, Zhu announced that Beijing will sanction people on a list of what it called "stubborn secessionists."
