US President Donald Trump said on Thursday the United States was having tremendous success in its trade negotiations with China, a day after U.S. and Chinese officials concluded three days of talks in Beijing, Reuters reported.

The meetings in China were the first face-to-face talks since Trump and Chinese President Xi Jinping met in Buenos Aires in December and agreed a 90-day truce in a trade war that has disrupted the flow of hundreds of billions of dollars of goods.

Trump, a Republican, has accused China of cheating the United States on trade and stealing U.S. intellectual property, though he often has said he has a good personal rapport with Xi.

“We’re negotiating and having tremendous success with China,” Trump told reporters as he left the White House on a trip to the U.S. border with Mexico on the 20th day of a partial shutdown of the U.S. government. He did not elaborate.
