Cui Tiankai

China’s ambassador to the U.S. warned the Trump administration against adopting a confrontational approach to the world’s second-biggest economy.

Cui Tiankai, the country’s ambassador in Washington, is its chief behind-the-scenes facilitator for the meeting that will bring together Mr. Xi and President Obama at Sunnylands starting June 7. 

Personnel changes for State Councilor, Foreign Minister-designate, and ambassador to the U.S. suggest that China wants to improve the optics of its relationship with the United States, if not the substance.
