US President Donald Trump says the US has found agreement on some of the toughest points in trade talks with China.
He said a deal could come in the next four weeks, but added some sticking points remained.
The Chinese echoed the optimism, with President Xi Jinping touting substantial progress, according to the Chinese state news agency Xinhua.
The US and China have been in talks since December trying to end a trade war that is hurting the global economy.
Trump said the US and China had agreed on “a lot of the most difficult points” but that “we have some ways to go”.
He was speaking from the White House, before a meeting with Chinese Vice Premier Liu He.
The US president said if there was a deal, he would hold a summit with Xi Jinping.
“This is an epic deal, historic – if it happens,” said Trump. “This is the Grand Daddy of them all and we’ll see if it happens. It’s got a very good chance of happening.”
Sticking points in negotiations in recent weeks have included how fast to roll back tariffs and how a deal would be enforced. Mr. Trump suggested at the press conference that some of these persisted.
He said it would be tough for the US to allow trade to continue with China in the same way as in the past, if a deal did not materialize.
