China denounced on Wednesday a visit by US lawmakers to Taiwan on a military aircraft, calling it a "clumsy show" that was doomed to fail.

A handful of "Taiwan independence" separatist forces and foreign politicians cannot change the solid fact 180 countries in the world are committed to the one-China principle, Foreign Ministry spokesman Wang Wenbin said at a daily news briefing, adding the spectacle was one distraction in the process of the country's reunification.

China strongly opposed this move and has lodged stern representations with the US, as it severely violates the one-China principle and stipulations in the three China-US Joint Communiques, Wang said.

Washington should immediately stop engaging in any official contacts with Taiwan and sending wrong signals to "Taiwan independence" forces, so as not to damage bilateral ties and peace and stability across the Straits, he said.

Wang said China's reunification is an unstoppable historical trend, with Taiwan an inalienable part of China's territory and the one-China principle an unshakable norm governing international relations.

Over 1.4 billion Chinese people, including Taiwan compatriots, share the overwhelming aspiration for national reunification, the spokesman said, adding even the Straits cannot disrupt it.

He urged relevant US lawmakers to understand the situation, saying colluding with "Taiwan independence" forces is a dangerous game and playing fire with separatists would end up burning themselves.

"Any adventurous and provocative move against the overriding trend of China's reunification is like an ant trying to shake a big tree, which is doomed to fail," he warned.
