US President Donald Trump and his Chinese counterpart Xi Jinping have agreed to halt new trade tariffs for 90 days to allow for talks, the US says.
At a post-G20 summit meeting in Buenos Aires, Mr Trump agreed not to boost tariffs on $200bn (£157bn) of Chinese goods from 10% to 25% on 1 January.
China will buy a "very substantial" amount of agricultural, industrial and energy products, the US says.
Meanwhile, Beijing says the two sides agreed to open up their markets.
It was the first face-to-face meeting between the two leaders since a trade war erupted earlier this year.
