China will make people who support Taiwan independence criminally liable for life, according to a spokesman for China's Taiwan Affairs Office. 

As tensions increase between the mainland and the self-ruled island China claims as its own, this is the first time China has spelled out real punishment for those perceived to be pro-Taiwan independence.

Taiwan's Premier Su Tseng-chang, Parliament Speaker You Si-kun, and Foreign Minister Joseph Wu were described as "stubbornly pro-Taiwan independence" by the office, which made public for the first time a list of those who fit this description.

China will penalise anyone on the list by denying them entry to the mainland and China's Special Administrative Regions of Hong Kong and Macau, said spokesperson Zhu Fenglian.

The people on the blacklist will not be able to work with mainland entities or people, and their companies or entities that fund them will not be allowed to profit from the mainland, she said.

For the most part, Taiwanese politicians rely on corporate donations to support their election campaigns. Doing business with the mainland generates profitability for many Taiwanese enterprises.

According to Zhu, China will also take any other appropriate steps against these individuals. "Those who forget their ancestors, betray the motherland, and split the country, will never end up well," she said, adding that "they will be spurned by the people and judged by history."
