Ahead of key trade talks in London, here are all the tariffs, counter-tariffs, dealmaking, and dealbreaking between the world’s two biggest economies.

The FTSE 100 opened slightly higher as the US and China prepare to hold trade talks in London. The UK’s blue-chip stock index climbed 0.1pc to 8,845.73 while the mid-cap FTSE 250 was flat at 21,159.10. Donald Trump said the talks in London “should go very well”.

The meeting comes against a backdrop of increasing trade hostility and heightened geopolitical tension, particularly around China’s tight grip on the supply of critical minerals.
