Uncertainty over Chinese vice-premier tour to US for trade talks

China's foreign ministry said on Monday a Chinese delegation is preparing to go to the United States for trade talks after U.S. President Donald Trump said he would raise tariffs on $200 billion worth of Chinese goods this week and target hundreds of billions more soon.

Ministry spokesman Geng Shuang, speaking at a regular news briefing, did not say if Vice Premier Liu He, who is China's lead official in trade negotiations with the United States, would be part of the delegation.
