China urges the Czech Republic to honor its promises to strictly restrain certain individual politicians from sabotaging China-Czech relations, Chinese Foreign Ministry spokesperson Lin Jian said during a regular press conference on Tuesday.

Lin made the remarks in response to a question about Taiwan's so-called vice president-elect Hsiao Bi-khim visiting the Czech Republic and giving a speech at a think tank. Lin said explicitly that Taiwan is a province of China and does not have a vice president.

Lin said that China strongly opposes official interaction of any form between China's Taiwan region and countries that have diplomatic relations with China, and this position is consistent and clear.

In multiple official documents, including the joint statements and joint communiqué between the government of China and the Czech government, the government of the Czech Republic solemnly committed to stick to the one-China policy , respect China's sovereignty and territorial integrity and recognize that Taiwan is an inalienable part of the Chinese territory.

China urges the Czech Republic to follow its commitment, strictly restrain certain politicians, immediately stop the egregious moves that undermine the national credibility of the Czech Republic and its relations with China. "We urge the Czech Republic to take effective measures to undo the negative influence of the incident," Lin said.

"Our message to 'Taiwan independence' separatists is that whoever engages in 'Taiwan independence' will be held accountable by history; whoever in the world creates 'one China, one Taiwan' will get burned for playing with fire and taste the bitter fruit of their own doing," Lin stressed.

Later on the same day, Chen Binhua, spokesperson for the State Council's Taiwan Affairs Office, said that the so-called diplomatic breakthroughs adopted by the DPP authorities in the Taiwan region, in collusion with external forces, to achieve the goal of "Taiwan independence" have undermined the fundamental interests of the Taiwan compatriots, which cannot change the fact that Taiwan is a part of China, and are not conducive to peace and stability in the Taiwan Straits.
