Trump-Xi summit: US and Chinese presidents hold closed-door talks in Washington DC

The summit between presidents Donald Trump and Xi Jinping covered trade, artificial intelligence and global conflicts. Mr Xi also urged the US to oppose Taiwan independence - a call that Taipei has swiftly rejected. Nick Harper and Olivia Siong report from Washington DC.
