The United States and China have agreed on a framework to implement their trade truce, officials on both sides said Wednesday, after concluding two days of talks in London to defuse tensions and ease export restrictions that threaten to disrupt global manufacturing.

High-level delegations from the United States and China are meeting in London to try and shore up a fragile truce in a trade dispute that has roiled the global economy.

Trade talks between the U.S. and China stretched through a second full day and into the evening in London on Tuesday as the two superpowers pushed for a breakthrough on duelling export controls that have threatened to unravel a delicate tariff truce.
