UPDATE 1-Trump says trade talks with China going 'very well'

President Donald Trump said on Tuesday that U.S. trade talks with China were going well as two top American officials reportedly plan a visit to China next week for a fresh round of talks.

U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin expect to fly to Beijing the week of March 25 to meet with Chinese Vice Premier Liu He, who will pay a return trip to Washington the following week, the Wall Street Journal said, citing Trump administration officials. Talks between China and the United States are in the final stages, with a target date for a deal by the end of April, according to the report.

"China's going very well. Talks with China are going very well," Trump said in response to a shouted question at the end of his White House news conference with Brazilian President Jair Bolsonaro. Washington and Beijing have slapped import duties on each other's products that have cost the world's two largest economies billions of dollars, roiled markets and disrupted manufacturing and supply chains.

Representatives of the U.S. Treasury and Office of the U.S. Trade Representative could not be immediately reached for comment. The White House had no immediate comment. (Reporting by Roberta Rampton; Writing by Doina Chiacu; Editing by Rosalba O'Brien and Grant McCool)
