BEIJING (Reuters) - U.S. Treasury Secretary Steven Mnuchin said in a tweet on Friday that he and U.S. Trade Representative Robert Lighthizer had concluded “constructive” trade talks in Beijing.

“I look forward to welcoming China’s Vice Premier Liu He to continue these important discussions in Washington next week,” he said in the tweet.

Mnuchin and Lighthizer were in the Chinese capital for the first face-to-face meetings between the two sides in weeks after missing an initial end-of-March goal for a summit between U.S. President Donald Trump and Chinese President Xi Jinping to sign a pact.
