U.S. President Donald Trump and his Chinese counterpart have set out starkly different visions for the future of global trade in speeches at a summit in Vietnam.
In a defiant address, Mr. Trump told the Asia-Pacific Economic Co-operation (APEC) meeting that the US would no longer tolerate "chronic trade abuses".
In contrast, Chinese President Xi Jinping said globalisation was irreversible.
Mr. Trump is currently on a five-nation Asia tour, with China one of his stops.
APEC brings together 21 economies from the Pacific region - the equivalent of about 60% of the world's GDP.
