BEIJING, March 7 (Xinhua) -- The one-China principle is a "red line" that must not be crossed in China-U.S. relations, State Councilor and Foreign Minister Wang Yi said Sunday, adding that the Chinese government will never compromise on the Taiwan question.

Wang made the remarks while responding to a media question about the U.S. policy on China's Taiwan, at a press conference held on the sidelines of China's annual legislative session.

Noting that there is only one China in the world and Taiwan is an inalienable part of China's territory, Wang said the two sides of the Taiwan Strait must be and will surely be reunified.

"This is the trend of history and the collective will of the entire Chinese nation," Wang said. "It will not and cannot be changed."

The one-China principle is the political foundation of the China-U.S. relations, a red line that must not be crossed, he said, adding that on the Taiwan question, there is no room for compromise or concession from the Chinese government.

Wang said China hopes that the new U.S. administration will appreciate the great sensitivity of the Taiwan question, and will abide by the one-China principle and the three Sino-U.S. communiques.

"We would hope to see a clear departure from the previous administration's dangerous practice of 'crossing the line' and 'playing with fire', and we hope that the Taiwan question will be handled prudently and properly," he added.
