Chinese Vice Foreign Minister Ma Zhaoxu on Thursday stated China's stance on the Taiwan question, Xizang, the South China Sea issue and the Ukraine crisis in a phone call with U.S. Deputy Secretary of State Kurt Campbell.

During the phone conversation, Ma demanded that the United States translate the "five-no" commitments made by U.S. President Joe Biden into real actions, respect China's sovereignty, security and development interests, and play a positive role in the stable development of China-U.S. relations instead of acting otherwise, said the Chinese Foreign Ministry in a statement.

Biden earlier pledged that the U.S. does not seek a "new Cold War" with China, nor does it seek to change China's system, that the revitalization of its alliances is not against China, that it does not support "Taiwan independence," and that it is not looking for conflict with China.

On the Taiwan question

Ma on Thursday stressed that the Taiwan question is at the core of China's core interests, and the first red line that cannot be crossed in China-U.S. relations.

"Taiwan independence" is a dead end, and connivance and support for "Taiwan independence" will backfire, he said.

The U.S. should fully see through the separatist nature of the Democratic Progressive Party authorities and its grave harm to cross-Straits peace and stability, abide by the three China-U.S. joint communiques, stop arming Taiwan, and act on its commitment of not supporting "Taiwan independence," said Ma.

On Xizang

The Chinese vice foreign minister said Xizang-related issues concern China's sovereignty and territorial integrity.

The U.S. should stop emboldening the "Tibetan independence" forces in any form and stop interfering in China's internal affairs taking Xizang-related issues as an excuse, he said.

On South China Sea

Ma said the root cause of the current tensions around Ren'ai Jiao is that the Philippines has abandoned the consensus reached with China and challenged China's sovereignty and territorial integrity by sending large amounts of construction materials to the illegally grounded vessel in an attempt to achieve permanent occupation of Ren'ai Jiao.

The U.S. side should stop emboldening and supporting the provocations of the Philippine side and take concrete actions to maintain peace and stability in the South China Sea, he said.

On Ukraine crisis

Ma said China's position on the Ukraine issue is objective and just.

The U.S. side should stop groundlessly smearing and scapegoating China, and stop obstructing the normal economic and trade exchanges between China and Russia, he said.

China firmly opposes the abuse of illicit unilateral sanctions and long-arm jurisdiction by the U.S. side, and will firmly safeguard the legitimate and lawful rights and interests of Chinese entities and individuals, he added.
