Chinese Premier Wen Jiabao said Sunday the referendum scheduled for March 20 by the Taiwan authorities under the pretext of democracy poses a threat to stability across the Taiwan Straits, and challenges the universally acknowledged one-Ch ina principle.

The premier said he appreciated the international opposition tothe referendum, and the open statement on the one-China principle made by the international community, including the United States, is conducive to maintaining peace and stability across the Taiwan Straits.

"I hope the United States and other countries would honor theircommitment to the one-China principle, and make due contribution to maintaining stability across the Taiwan Straits and to China's peaceful reunification," Wen said at a press conference after the closing of the national legislature's annual session.

The Taiwan issue, left over from China's civil war, is the internal affairs of China, and will eventually be resolved by the Chinese people on their own, said the premier.

China has sovereignty over Taiwan, which has been recognized bythe international community, he said.
