Speaking on the Taiwan question, Wang warned, "There is no room for compromise or concession from the Chinese government." He said the one-China principle is the political foundation of the China-US relations and is "a red line that should not be crossed".

Wang said the two sides of the Taiwan Straits must be and will surely be reunified. "This is the trend of history and the collective will of the entire Chinese nation. It will not and cannot be changed," he said.

The new US administration is expected to "appreciate the great sensitivity" of the Taiwan question and abide by the one-China principle and the three landmark China-US communiques, he said.

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

In response to a question about potential risks in the South China Sea situation as the Biden administration shifts focus back to Asia, Wang said, "Countries in the region and around the world can all see clearly in recent years that the factors of instability and security risks in the South China Sea come mainly from outside the region."

China and all members of the Association of Southeast Asian Nations are expected to work simultaneously on both fronts－first, removing distractions to advance talks on the expected text of the Code of Conduct in the South China Sea, and second, ensuring the overall stability in the sea, Wang said.

When asked about Beijing's plan to bolster collaboration with the US and Europe on tackling climate change, Wang said China welcomes the US return to the Paris Agreement (on climate change) and expects that the US will shoulder its responsibility and make its due contribution.

"We hope that renewed China-US cooperation on climate change will bring a positive 'climate change' to their relations," he added.
