China has lodged stern representations with the United States over Washington's statement urging United Nations (UN) members to support China's Taiwan region's participation in the UN system, Chinese Foreign Ministry spokesperson Zhao Lijian said Wednesday.

China expresses strong dissatisfaction and firm opposition to the statement, which sent a critical wrong signal to "Taiwan independence" forces, Zhao told a regular press briefing.

"If the U.S. continues on the path of playing the 'Taiwan' card, it would certainly pose a subversive, huge risk to China-U.S. relations," the spokesperson said.

He urged the U.S. to stop issuing irresponsible and wrong statements, or helping Taiwan expand the so-called international space, and take concrete actions to safeguard the political foundation of China-U.S. relations. 

Earlier, the spokesperson of the Chinese Embassy in the United States issued a statement on the issue, saying Washington is blatantly challenging the one-China principle.

Regarding the Taiwan question, the UN system, its agencies and secretariat should abide by the one-China principle and UNGA Resolution 2758, the statement said. 

"The United Nations is an intergovernmental international organization composed of sovereign states. Resolution 2758 adopted by the General Assembly in 1971 has solved once and for all the issue of the PRC's representation in the UN in political, legal and procedural terms," it said. "The system, agencies and the Secretariat of the UN should abide by the one-China principle and UNGA Resolution 2758 when dealing with Taiwan-related affairs."

About 180 countries including the U.S., recognize that there is only one China in the world and Taiwan is an inalienable part of China's territory and the participation of the Taiwan region in activities of international organizations must be handled in accordance with the one-China principle, the statement said. 

"We urge the U.S. side to adhere to the one-China principle and provisions of the three Sino-U.S. joint communiques and abide by Resolution 2758," it said

The spokesperson also urged the U.S. to stop making irresponsible and erroneous remarks and take concrete actions to maintain the overall situation of Sino-U.S. relations as well as peace and stability across the Taiwan Strait.
