The commerce ministry confirmed in a brief statement that Vice Premier Liu He, President Xi Jinping's trade pointman, would visit the US on Thursday and Friday.
The trip is taking place a day later than expected after President Donald Trump jolted global markets by announcing that tariffs on $200 billion in Chinese merchandise will more than double to 25% on Friday.
US-China trade war ‘bad for the whole world’
"China always believes that mutual respect, equality and mutual benefit are the premise and the basis for reaching an agreement. Adding tariffs will not solve any problem," Chinese Foreign Ministry spokesman Geng Shuang said at a regular press briefing.
Confirmation of Liu's travel plans lifted Asian stock markets as his presence could raise hopes that a deal is still possible.
The tariffs announcement tanked stock markets worldwide on Monday and worried US farmers and businesses which have been banking on a resolution to the year-long conflict that has engulfed $360 billion in two-way trade.
US officials had said the world's two largest economies were close to an agreement but Beijing reversed course in recent days.
"Over the course of the last week or so, we've seen an erosion in commitments by China, I would say retreating from commitments that have already been made in our judgement," US Trade Representative Robert Lighthizer was quoted as saying in media reports on Monday.
He said the tariffs would increase at 12:01 am (0401 GMT) on Friday.
Treasury Secretary Steven Mnuchin described the negotiations as 90% complete but told reporters that in recent days the talks went "substantially backward", according to the media reports.
Complaining that talks were moving too slowly because China was trying to "renegotiate" the terms, Trump vowed on Sunday to ratchet up existing tariffs this week and extend the 25% punitive duties to the remaining $350 billion in Chinese goods imported into the country each year.

Speaking in Paris, International Monetary Fund chief Christine Lagarde said "tensions between the United States and China are the threat for the world economy", and recent "rumours and tweets" made an agreement between the countries less likely.
Comments from officials in recent weeks indicated the two sides were making progress towards an agreement aimed at addressing longstanding concerns about the forced transfer or outright theft of American technology as well as reducing the US trade deficit with China.
"It is normal for the two sides to have divergences. China does not evade problems and is sincere in continuing consultations," Geng said.
But William Reinsch, trade policy expert at the Centre for Strategic and International Studies, said China will never meet all the US demands.
"At some point, the president is going to figure out that they're not going to give him everything he wants," he told AFP. That will put Trump in "a precarious political position", whether "to accept an agreement that will be criticised as weak, or not to have an agreement and be criticised for failing".
