US President Donald Trump repeated his military threats against Iran ahead of a visit to China, the Islamic Republic’s largest oil customer and a key diplomatic partner.

Iran will either “make a good deal” with the US or face devastation, Trump said on Tuesday. The war on Iran, which has sent energy prices soaring because of Tehran’s effective closure of the Strait of Hormuz, will be high on the agenda of the talks between Trump and Chinese President Xi Jinping.
