President Donald Trump said he made "fantastic trade deals" with Xi Jinping, as the pair met on Friday at final meetings of a superpower summit that according to the US leader has also reaped a Chinese offer to help open the Strait of Hormuz. Trump had arrived in Beijing seeking to seal deals in sectors including agriculture, aviation and artificial intelligence, as well as to contain differences between the two sides in a number of tense geostrategic areas -- not least the Middle East war.
