United States President Donald Trump is in China for a three-day summit with Chinese President Xi Jinping, marking their seventh face-to-face meeting and the first visit by a US leader to China since 2017. We look at the past encounters between the leaders of the world’s two biggest powers.

The summit also comes as tensions between Washington and Tehran continue to rise despite a temporary ceasefire announced in April. Trump has rejected Iran’s latest response to a US peace proposal, while negotiations remain stalled over the Strait of Hormuz and Tehran’s nuclear programme.

Meanwhile, regional tensions are growing in the Gulf, with Iranian officials warning the United Arab Emirates against supporting US or Israeli military operations.
