What Happened In a May 5 tweet, U.S. President Donald Trump renewed a threat to raise tariffs on Chinese imports, specifically mentioning increasing the levy on $200 billion in Chinese goods to 25 percent at the end of the week. The president followed that with a suggestion that the United States could subject remaining Chinese goods exports (worth some $300 billion to $350 billion) to annual tariffs, a move subject to public comment that could take up to three months to implement. The tweet came ahead of a planned trip by a high-level Chinese delegation, including chief trade negotiator Liu He, to Washington for an anticipated round of talks to address lingering trade issues between the United States and China. Instead, reports have indicated, the delegation departed for the United States without Liu, although he reportedly will travel to Washington at the end of the week.
