China is accelerating its efforts to end the Iran war, walking a diplomatic tightrope as it prepares for a summit next month with US President Donald Trump while trying not to alienate Tehran.

President Xi Jinping’s mid-May meeting with Trump is shaping Beijing’s approach to the Middle East conflict even as the world’s top crude oil importer, reliant on the Middle East for half its fuel, seeks to safeguard its energy supplies, analysts say.

China’s modulated approach to the war has protected its back-channel leverage enough that Trump credited Beijing with helping to get Iran to last weekend’s peace talks in Pakistan.

“You’ve heard President Trump repeatedly mention how the Chinese talked to the Iranians,” said Eric Olander, editor-in-chief of the China-Global South Project, an independent organisation that analyses China’s engagement in the developing world. “That puts them in the room with negotiators, even if it’s not a seat at the table.”

Considering Trump transactional and susceptible to flattery, China is seeking to advance its goals on trade and its claims on Taiwan at the summit, people familiar with China’s thinking told Reuters. The dominant view in Beijing is to “butter him up, give him a red-carpet welcome and preserve strategic stability”, one person said.

China’s foreign ministry did not respond to questions about its diplomacy ahead of the summit, the first visit by a US president in eight years. Trump says it will take place May 14 and 15.

With the US naval blockade of Iranian ports as a direct and growing threat, China has engaged in a flurry of diplomatic activity and refrained from strong criticism of Trump’s conduct of the war so that the summit, postponed once by the conflict, can go smoothly, analysts say.

Xi broke his silence on the crisis on Tuesday with a four-point peace plan that calls for upholding peaceful coexistence, national sovereignty, the international rule of law and balancing development and security.

Foreign Minister Wang Yi has held nearly 30 calls and meetings with counterparts seeking a ceasefire, according to a Reuters count, while special envoy Zhai Jun has toured five Gulf and Arab capitals.

Travelling at one point by road to avoid contested airspace, Zhai could hear air-raid sirens, he told reporters. Xi announced his peace plan in a meeting with Abu Dhabi’s Crown Prince, Sheikh Khaled bin Mohamed bin Zayed Al Nahyan, as he sought to deepen ties with a rival to Iran while pressing Tehran towards dialogue. Still, some analysts say, Iran needs China more than China needs Iran, allowing Beijing to press for a ceasefire while protecting the summit with Trump.
