President Donald Trump instructed aides on Thursday to proceed with tariffs on about US$200 billion more in Chinese products despite his Treasury secretary’s attempt to restart talks with Beijing to resolve the trade war, according to four people familiar with the matter.

But announcement of the new round of tariffs has been delayed as the administration considers revisions based on concerns raised in public comments, the people said.

Trump met with his top trade advisers on Thursday to discuss the China tariffs, including Treasury Secretary Steven Mnuchin, Commerce Secretary Wilbur Ross and U.S. Trade Representative Robert Lighthizer, the people said. Mnuchin has led a recent overture to the Chinese to re-start trade talks.

The public comment period for a list of tariffs on about US$200 billion in Chinese goods closed last week, and Trump said the duties would be imposed “soon.” The new round would be in addition to US$50 billion in Chinese goods that already face a 25 per cent duty. U.S. stocks erased gains on the news.

The Chinese have retaliated with tariffs on an equivalent amount of U.S. exports, and have promised to match future rounds of U.S. duties.

Before his meeting on Thursday, Trump boasted on Twitter that he has the upper hand in the trade feud with Beijing and feels “no pressure” to resolve the dispute.

His comment tempered cautious optimism among investors over the U.S. government’s proposal for another round of talks with Beijing. Disclosure on Wednesday that the U.S. sought to renew the talks rallied U.S. stocks and emerging-market assets.

Trump threatened a third tranche of tariffs on another US$267 billion of Chinese imports last week, which would mean levying duties on nearly everything China exports to the U.S. Trump said at the time those tariffs were “ready to go on short notice,” but the administration hasn’t yet published a list for public comment.

Efforts to end the dispute have fizzled so far. Officials from both countries have met four times for formal talks, most recently in August, when Treasury’s undersecretary for international affairs, David Malpass, led discussions in Washington with Chinese Vice Minister Wang Shouwen.

The White House has sought to pressure Beijing to reduce its trade surplus with America and protect intellectual property rights of U.S. companies, which it says are abused in China.
