Trump says US-China deal 'is done'

US President Donald Trump has said a deal with China "is done" after two days of talks between top officials in London.

Trump said that, subject to final approval from President and himself, the US will get the rare earth metals it needs, while Chinese students can take up their places at American colleges.

Earlier, the US and China said they had agreed in principle a framework for de-escalating trade tensions between the world's two biggest economies.

Last month, Washington and Beijing agreed a temporary truce over trade tariffs but each country has since accused the other of breaching the deal.
