Trade talks between the US and China have broken up without a deal, with the US warning that “very difficult issues” remain unresolved.
The talks in China this week were aimed at securing a new deal before further US tariffs are imposed on 1 March.
China said negotiations would now continue in the US next week.
“We feel that we have to make headway on some very, very important and very difficult issues,” said top US trade negotiator Robert Lighthizer.
However, he said he was “hopeful” of progress.
President Xi Jinping said he hoped talks next week would “continue to work hard to promote a mutually beneficial and win-win agreement.”
The two countries have been locked in an escalating trade war, imposing duties on billions of dollars worth of one another’s goods.
