President Donald Trump announced Thursday that the United States and China have formally signed a trade agreement, bringing an end to months of negotiations. The deal cements the informal understanding reached earlier during talks in Geneva,

It follows initial talks in Geneva in early May that led both sides to postpone massive tariff hikes that were threatening to freeze much trade between the two countries.

Donald Trump said on Thursday the US and China had signed a trade deal two weeks after saying they had reached an understanding in London about how to implement a ceasefire in the countries’ dispute. “We just signed with China yesterday,” the president said at the White House on Thursday, without providing any details.
