On Tuesday, the Communist Party of China Central Committee imposed sanctions on Taiwan diehards on the Chinese mainland's list of diehard separatists, adding more political figures such as Bi-khim Hsiao and Koo Li-hsiung, as well as punishing measures on individuals such as Su Tseng-chang, You Si-kun and Joseph Wu. In order to protect the peaceful development of the cross-Straits relations and the immediate interests of the people on both sides of the Straits, the office included the political figures Bi-khim Hsiao, Koo Li-hsiung, Tsai Chi-chang, Ker Chien-ming, Lin Fei-fan, Chen Jiau-hua and Wang Ting-yu into the list of diehard Taiwan independence diehards. The office has also imposed punitive measures on political figures like Su Tseng-chang, You Si-kun and Jaushieh Joseph Wu, who had already been on the list, by banning them and their family members from entering the mainland, Hong Kong and Macao SARs. Their affiliated institutions are restricted from forging cooperation with relevant organizations and individuals on the mainland. The office said that enterprises related to them, as well as their sponsors, are not allowed to engage in profit-making activities on the mainland. Other punitive measures will be taken and those figures will be held to lifelong accountability according to law. Hsiao Bi-khim, Taiwan's representative to the US, was recently criticized by the central government's top office on Taiwan affairs due to her frequent spread of claims about Taiwan independence. She has recently pushed US arms sales to Taiwan and accelerated the visit of US House Speaker Nancy Pelosi to Taiwan, which is a serious provocation that shows the US commitment to China on the Taiwan question. Sanctions are also imposed on the president of the Taiwan Foundation for Democracy and the secretary general of the International Cooperation and Development Fund. They are not allowed entry into the mainland and the special administrative regions of Hong Kong and Macao, said a spokeswoman. Jaushieh Joseph Wu is the chairman of the International Cooperation and Development Fund. The latest announcement came after China resolutely responded to the continuous provocation by the US on Taiwan, most recently seen in sending another delegation of US lawmakers to the island just 12 days after Pelosi visited, which seriously trampled on the one-China principle and sabotaged the fundamentals of the China-US relations. The action to seek Taiwan independence is the biggest obstacle to China's reunification and a grave danger to the national rejuvenation, said a spokesman for the CPC Central Committee in Taiwan, the work office of the Taiwan Work Office. Their activities became more egregious during the visit by Pelosi to China's Taiwan region, further exposing their obstinate nature in seeking Taiwan independence. The Chinese mainland will never tolerate any activity aimed at reunification, will never allow any external force to interfere in its national reunification, and will leave no room for separatist activities seeking Taiwan independence in any form, said the spokesperson. According to media reports, the mainland will take strict measures to bring the diehard secessionists to justice, in accordance with the Anti-Secession Law, the Criminal Law and the National Security Law.
