A dinner meeting Saturday between US President Donald Trump and his Chinese counterpart Xi Jinping to discuss their growing trade war went "very well", White House top economic advisor Larry Kudlow said.
Kudlow's comment to journalists, as Trump and his delegation were about to take off for Washington from Buenos Aires, was the first public reaction from the high-stakes dinner lasting more than two hours.
White House spokeswoman Sarah Sanders said she expected to release a statement soon. There was no immediate word from China's government.
Trump and Xi, who were in the Argentinian capital over the last two days for a summit of G20 countries, had gone into the meeting in a bid to pull the world's top two economies from the brink of a full-fledged trade war.
Both leaders expressed optimism as they and top aides sat down at a long hotel table adorned with flowers.
"We will probably end up ending up getting something that will be good for China and the United States," Trump said.
Xi stated that they shared tremendous responsibility to find a solution. "Only with cooperation between us can we serve the interest of both peace and prosperity," he said.
The meeting, featuring a menu of sirloin steak, caramel rolled pancakes and Argentinian wine, went on longer than scheduled.
