“When the White House announced this week that President Trump had sent President Xi Jinping of China a letter wishing him a happy Chinese New Year, it did not disclose a major reason for the friendly gesture: Mr. Xi has not gotten on the phone with Mr. Trump,” the New York Times reports.

“Stung by Mr. Trump’s unorthodox telephone call with the president of Taiwan and his subsequent assertion that the United States might no longer abide by the “One China” policy, Mr. Xi has not spoken to Mr. Trump since Nov. 14, the week after he was elected. Administration officials say they believe he will only do so after Mr. Trump publicly commits to recognizing a single Chinese government in Beijing.”

“China warned Donald Trump against using the One-China policy regarding Taiwan as a bargaining chip in trade talks, a swift response that indicates Beijing is losing patience with the U.S. president-elect as he breaks with decades of diplomatic protocol,” Bloomberg reports.

Said a spokesperson: “Adherence to the One-China policy is the political bedrock for the development of the China-U.S. relationship. If it is compromised or disrupted, the sound and steady growth of the China-U.S. relationship as well as bilateral cooperation in major fields would be out of the question.”
