"We've got to do everything we can to build up the American economy and stop sitting here and trying to build up the Chinese economy", he said.

News that China appeared to be backtracking off its verbal commitments was delivered to Trump in a briefing at the end of last week from his chief trade negotiator Robert Lighthizer, who cast the developments as a disappointing move after what had appeared to be weeks of progress.

Mr Trump, in a post on Twitter last Sunday, said he planned to raise tariffs tomorrow on US$200 billion (S$272 billion) worth of Chinese goods to 25 per cent from 10 per cent. That also sounds grave on the surface because of trade war implications.
"We're not breaking off talks at this point". The sources told Reuters the extent of the setbacks in the revised text were serious and that Trump's response was not merely a negotiating strategy. That hike triggered a brief slowdown in the Chinese economy, prompting fears of a global economic downturn, but the renewed talks between the world's two largest economies has steadied markets in recent months.
