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

Both countries are under pressure to relieve tensions, with the global economy under stress from Chinese control over the rare-earth mineral exports and investors anxious about Trump's tariffs.
