Trump says US-China trade deal is close, but market nosedives

Beijing sees US president as impulsive and fears he could pull out of any deal, reports say

A trade deal between the US and China is imminent and only delayed by the need to find a venue for a signing ceremony, according to Donald Trump.

After almost two years of wrangling over US import tariffs on Chinese goods, which sparked a tit-for-tat row between the world's largest trading nations, the two sides were close to a comprehensive long-term trade agreement, the president said.
