A Chinese trade delegation abruptly canceled a visit on Friday to US farms in Montana and Nebraska, cutting short their US trip, fueling pessimism about the prospect of a trade truce between the world's two largest economies. The trip was to prepare for further negotiations between senior officials next month. Investors had earlier expected a potential cooling of US-China trade tensions as the two sides gear up for talks. But the sudden change in the trip dampened investor hopes for a breakthrough in the negotiations. Earlier in the day, President Donald Trump had said the United States was looking for a "complete deal" with China and not a partial one. Lack of progress in Sino-U.S. trade talks prompted investors to sell shares.
