Trump's volatile visit to beijing: a summit of geopolitical peril

Donald Trump's erratic presidency has long been a global wrecking ball, smashing up international order without regard for the consequences. His upcoming summit with Xi Jinping in Beijing promises to be a perfect storm of diplomatic peril, as the US president's desperate bid for a foreign policy triumph collides with China's strategic interests.

Trump's weak hand

Trump's hopes for a victorious trade deal are overshadowed by his latest military misadventure, the fraught standoff between China and Taiwan. He needs Xi's assurance that China won't arm Iran if fighting resumes, and for Beijing's help keeping the Strait of Hormuz open as part of a mooted framework peace deal.

China is urging both sides to embrace a negotiated settlement, hosting direct talks with Iran's foreign minister and backing Pakistani intermediaries. Gulf states are counting, like Trump, on Beijing's ability to influence its Iranian ally, with which it launched a
