The vice premier of China is set to lead a delegation to the United States on Jan. 30-31 for a second round of negotiations aimed at ending the countries' trade conflict, the Chinese commerce ministry said on Thursday.

Ministry spokesperson Gao Feng confirmed the visit at a press conference in Beijing and said that Vice Premier Liu He would meet US Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin during the trip.

Liu, one of the principal economic advisers of President Xi Jinping, was present during the first round of trade talks held between Jan. 7-9 in Beijing.

In spite of the optimism generated ahead of the talks, no agreement was reached.

Xi and US President Donald Trump agreed on Dec. 1 to a 90-day truce in the trade conflict, which marks Mar. 1 as the deadline for finalizing a trade deal.

Since the truce, China has undertaken several goodwill measures including lowering tariffs on vehicles imported from the US, resuming the purchase of soya and submitting a bill to ban the forced transfer of technology.

Trump temporarily suspended the 10-25 percent tariff increase on Chinese products valued at $200 billion but threatened to discontinue the plan if a trade agreement is not reached before the expiry of the 90-day term.
