BEIJING (AP) — President Donald Trump is set to leave on Tuesday for Beijing to meet with President Xi Jinping after weeks of trying, and failing, to persuade the Chinese government to use its considerable leverage to prod Iran to agree to U.S. terms to end the 2-month-old war — or, at the very least, reopen the Strait of Hormuz.

Trump has veered between venting that China, the world’s biggest buyer of Iranian oil, hasn’t done more to get the Islamic Republic in line and acknowledging that Xi’s government helped de-escalate the conflict last month by nudging Tehran back to ceasefire talks when negotiations wobbled.

But ahead of the U.S. leader’s high-stakes visit, the White House has set low expectations that Trump will be able to persuade Xi to change China’s posture.

Instead, Trump’s Republican administration seems determined not to let differences on Iran overshadow efforts to make headway on other difficult matters in the complicated relationship — ranging from trade to further Chinese cooperation to block exports of fentanyl precursors.

“We don’t want this to be something that derails the broader relationship or the agreements that might come out of our meeting in Beijing,” U.S. Trade Representative Jamieson Greer said on Bloomberg TV last week.

US administration sanctioned China ahead of the trip

Beijing publicly insists that it wants to see the war end and has been working diplomatically behind the scenes to help its ally Pakistan push to broker a peace agreement. It has also sent a “subtle message of discontent to Iran” for closing the Strait of Hormuz and to the U.S. for its blockade of Iranian shipping, said Ahmed Aboudouh, a specialist on China’s influence in the Middle East with the London-based Chatham House think tank.

“They are very cautious, risk averse, and they don’t want to be involved in anything that would drag them into something that they don’t consider their problem,” he said.

Meanwhile, Kuwait on Tuesday accused Iran of dispatching an armed paramilitary Revolutionary Guard team to launch a failed attack earlier this month on an island in the Middle East nation that is home to a China-funded port project. Iran didn’t immediately acknowledge the allegation by Kuwait, which came under repeated attack by Iran in the war and even during the shaky ceasefire still holding in the region.

In recent days, Secretary of State Marco Rubio and Treasury Secretary Scott Bessent have stepped up their calls for China to use its influence to help reopen the strait, through which about 20% of the world’s crude flowed before the war began.

The State Department announced on Friday it was sanctioning four entities, including three China-based firms, for providing sensitive satellite imagery that enables Iranian military strikes against U.S. forces in the Middle East. Earlier, the Treasury Department moved to target Chinese oil refineries accused of buying oil from Tehran, as well as shippers of the oil. The sanctions cut off the companies from the U.S. financial system and penalize anyone who does business with them.

Beijing has called the sanctions “illegal unilateral pressure” and enacted a blocking statute — passed in 2021 and never used until now — that prohibits any Chinese entity from recognizing or complying with the sanctions.

Ahead of Trump’s arrival, Chinese Foreign Minister Wang Yi last week hosted his Iranian counterpart, Abbas Araghchi, in Beijing. The Chinese foreign minister used the moment to defend Iran’s right to develop civilian nuclear energy.

Xi has also offered implicit criticism of the U.S. over the war. He has said that safeguarding international rule of law is paramount, adding it “must not be selectively applied or disregarded,” nor should the world be allowed to revert “to the law of the jungle.”

China and the US want to avoid a return to a tariff war

Trump on Monday downplayed differences with China over Iran and underscored that Xi wants to see the strait reopened. “He’d like to see it get done,” Trump said of the Chinese leader.

Like Trump, Xi also has plenty of reason to not let differences over Iran impact other facets of the relationship, analysts say. China imports about half of its crude oil and almost one-third of its liquefied natural gas from Middle Eastern countries affected by the closure of the strait, according to China’s General Administration of Customs.

Beijing wants to guard against further deterioration of the U.S.-China relationship — something that would add further challenges to its economy.

“(Xi) wants the summit to validate China’s superpower status, preserve the tariff predictability, and to reaffirm that Washington has to deal with Beijing on Beijing’s terms,” said Craig Singleton, senior director for the Foundation for Defense of Democracies’ China program

Yet, since the U.S. and Israel launched strikes on Iran in late February, there have been difficult moments between Trump and Xi that threatened to set back the relative stability in their relationship.

China has long supported Iran’s ballistic missile program and backed it with dual-use industrial components that can be used for missile production, according to the U.S. government.

Last month, Trump threatened to impose a 50% tariff on China after reports that Beijing was preparing to deliver a shipment of new air defense systems to Iran, but he later backed away from the threat, claiming that he had received written assurance from Xi that he would not provide Tehran with weaponry. Days later, Trump said cryptically that the U.S. Navy had intercepted a Chinese vessel carrying a “gift” for Iran. He has not offered further explanation.

Both Trump and Xi may be eager to avoid creating dark economic clouds, as they did last year, when the two powers appeared on the precipice of a massive trade war.

Trump had set tariffs on Chinese goods at 145%, and China announced a further tightening of rare-earth export controls that would have hurt U.S. industry — before the governments backed off from inflicting maximalist penalties on each other. The two sides reached a fragile truce in their long-running trade disputes in October.

Trump and other administration officials have made the case that the Iran conflict — particularly the closure of the strait — has caused greater harm to China and its Pacific neighbors than it has to the United States, which is far less dependent on Middle East oil and has an export-driven economy.

“You can’t buy from them if you can’t ship it there, and you can’t buy from them if your economy is being destroyed by what Iran is doing,” Rubio told reporters last week, making the case that it was in China’s interest for Iran to let traffic resume.

But for now, China has shown little interest in wading deeper into the conflict and has appeared reluctant to be seen siding with Washington.

“It will be difficult to get the Chinese deeply involved under any circumstances,” said Kurt Campbell, a former deputy secretary of state during President Joe Biden’s Democratic administration and chair of The Asia Group. “They will want to be careful because they can see political quicksand as well as the next guy.”
