BEIJING, Dec. 21 (Xinhua) -- China expresses serious concerns over the U.S. side's recent negative words and actions on issues related to China's Taiwan, Hong Kong, Xinjiang and Tibet, Chinese President Xi Jinping said Friday.

In a phone conversation with his U.S. counterpart, Donald Trump, Xi noted that the U.S. behaviors have interfered in China's internal affairs and harmed China's interests, which is detrimental to the mutual trust and bilateral cooperation.

China hopes that the United States will seriously implement the important consensuses reached by the two leaders over various meetings and phone conversations, pay high attention and attach great importance to China's concerns, and prevent bilateral relations and important agendas from being disturbed, Xi said.
