WASHINGTON – China is intensifying its diplomacy around the Iran war, unveiling a five‑point proposal with Pakistan, courting support from Gulf governments and opposing a United Nations plan that would authorize the use of force to reopen the Strait of Hormuz. It is Beijing’s latest bid to cast itself as a crisis manager on the world stage even as Washington signals little interest in Chinese mediation.
Beijing’s push comes after a major escalation on Friday, when Iran shot down two U.S. military aircraft five weeks into the war. President Donald Trump told NBC News that the shoot‑downs would not affect negotiations with Tehran, days after declaring in a national address that the United States has “beaten and completely decimated Iran.”
Analysts say China sees opportunity, and risk. “The war with Iran is the priority of all countries in and outside the region,” said Sun Yun, director of the China program at the Stimson Center. “It is an opportunity China will not miss to demonstrate its leadership and diplomatic initiative.”
Why the stakes are global
The Strait of Hormuz remains the world’s most critical oil chokepoint and a barometer for global economic security. In the first half of 2025, an average of about 20-21 million barrels per day of crude oil and petroleum products transited the strait-more than a quarter of seaborne oil and around a fifth of global consumption-alongside a significant share of global LNG flows from Qatar, according to the U.S. Energy Information Administration. Any prolonged disruption ricochets through energy prices, shipping insurance and supply chains far beyond the Middle East, with direct implications for inflation, central bank policy and fiscal planning from Washington to Brussels to Beijing.
China, the world’s largest crude importer since 2017, is partly cushioned by diversified suppliers and a sizeable strategic reserve. But extended energy shocks and shipping disruption would feed through to costlier inputs and weaker global demand-pressure points for an export‑heavy economy that relies on open sea lanes for both energy and manufactured exports. The International Energy Agency has already warned that closing Hormuz poses an exceptional threat to global energy security and triggered a coordinated emergency release from members’ reserves in March, a step that requires governments to weigh short‑term price stability against longer‑term resilience of their strategic stocks.
Washington’s stance: cool to Chinese mediation
U.S. officials describe the administration’s posture toward the Chinese‑Pakistani effort as “agnostic,” neither endorsing nor rejecting it, while underscoring there is little appetite to boost Beijing’s diplomatic stature in the Gulf. That could shift if Trump weighs in before his planned summit with Chinese President Xi Jinping in mid‑May, a trip he already postponed once as the war escalated. For the White House and Congress, any perceived legitimization of a Chinese‑brokered process would intersect with domestic debates over great‑power competition, sanctions policy on Iran and the future role of U.S. forces in the Middle East.
Danny Russel, a former senior U.S. diplomat, called Beijing’s push “performative,” likening the five‑point proposal to China’s 2023 “position paper” on Ukraine that drew headlines but few results.
“Its narrative is that while Washington is reckless, aggressive and heedless of the cost to others, China is a principled and responsible champion of peace,” he said. “What we are seeing from China is messaging, not mediation.”
A spokesperson for China’s embassy in Washington countered that Beijing has been working “tirelessly for peace” since fighting began, framing the initiative as consistent with China’s long‑stated preference for negotiated solutions and opposition to unilateral military action.
Beijing’s calculus on Hormuz
Chinese officials argue they are more insulated than others from a temporary Hormuz disruption after diversifying supplies-including from Russia, Saudi Arabia and Iraq-and building strategic stocks. At the same time, China imports only a fraction of its oil directly from Iran and has been exploring arrangements with Tehran to ensure safe passage for Chinese‑flagged vessels, even as global shipping faces surging insurance costs and rerouting. The longer the strait remains constrained, the more severe the macroeconomic drag becomes for China and major Asian customers dependent on Gulf energy, increasing pressure on policymakers in Beijing to manage growth, stabilize currency markets and protect critical industries from energy‑price spikes.
What China is doing
Since the war broke out, Foreign Minister Wang Yi has phoned counterparts in Russia, Oman, Iran, France, Israel, Saudi Arabia and the United Arab Emirates, hosted Pakistan’s foreign minister in Beijing to shape a joint five‑point plan, and dispatched a special envoy across the region. He also sought European buy‑in, raising the plan with EU foreign policy chief Kaja Kallas, and pressed Gulf leaders for de‑escalation and a cease‑fire. Kallas, who took office as the EU’s High Representative in December 2024, is now a key European interlocutor for all Iran‑related diplomacy, reflecting the European Union’s attempt to keep a seat at the table in a crisis that directly affects its energy security and maritime trade.
- China’s recent mediation track record includes brokering the March 2023 agreement that restored diplomatic ties between Saudi Arabia and Iran-an achievement Beijing cites to bolster its peacemaker credentials and to argue that non‑Western powers can successfully manage regional rivalries.
- Beijing’s 12‑point “position paper” on Ukraine in February 2023 is the template critics invoke to argue that China’s proposals tend toward broad principles rather than actionable steps, raising questions over how its Iran plan would translate into verifiable commitments on the ground.
The U.N. debate over reopening the strait
At the United Nations, Bahrain initially circulated a draft Security Council resolution authorizing countries to use “all necessary means”-diplomatic shorthand under Chapter VII of the U.N. Charter-for potential force to secure navigation in and around Hormuz. After opposition from China and Russia, Manama significantly watered down the text to permit defensive-but not offensive-measures to protect shipping. A vote was postponed until next week, extending uncertainty for shipowners, insurers and energy ministries calibrating contingency plans.
Any mandate to escort or protect vessels would invoke the Council’s Chapter VII authority, which allows measures up to and including armed force when non‑military steps prove inadequate. While there is precedent for U.N. authorizations to repress piracy off Somalia’s coast and for states to conduct land‑based actions against pirate infrastructure, extending such authority to reopen an international strait would mark a significant escalation with complex legal and operational ramifications. It would also test unity among the Council’s permanent members at a moment when great‑power rivalry routinely spills into debates over sanctions, arms embargoes and peacekeeping mandates.
Law of the sea-and its limits
International law generally guarantees “transit passage” through straits used for international navigation, a regime codified in the U.N. Convention on the Law of the Sea (UNCLOS). But Iran has signed, not ratified, UNCLOS and has long argued that the transit‑passage regime does not automatically apply to non‑parties-complicating enforcement in Hormuz, where both Tehran and Washington are outside the treaty framework and rely on customary international law. That legal grey zone leaves navies, shipping companies and insurers navigating overlapping claims and raises the stakes of any miscalculation between Iranian forces and foreign warships asserting freedom of navigation.
History’s warning from the 1980s Tanker War
The Gulf has been here before. During the Iran‑Iraq “Tanker War” of 1987-88, the United States reflagged and escorted Kuwaiti tankers under Operation Earnest Will and later fought the largest U.S. surface naval battle since World War II in Operation Praying Mantis after an American frigate struck an Iranian mine. Those operations underscore both the feasibility and the risks of protecting commercial shipping under fire, highlighting how rapidly limited protection missions can widen into direct confrontation and force governments to clarify rules of engagement, burden‑sharing and exit strategies.
Regional reactions and Beijing’s endgame
China and Russia have warned that a robust U.N. mandate could be exploited by outside powers to widen the war. Beijing instead argues that reopening Hormuz requires a cease‑fire and a return to diplomacy under U.N. auspices, positioning its joint initiative with Pakistan as a complementary track to formal Council deliberations rather than a rival process. For Chinese officials, reducing violence before Trump’s mid‑May visit to China would lower the risk of further delays to high‑level engagement and strengthen Beijing’s claim that it can manage crises that directly affect the global economy.
Whether Beijing’s initiative moves beyond messaging to mediation will hinge on traction with Gulf capitals-especially Saudi Arabia and the UAE-buy‑in from Europe, and a decision in Washington to tolerate a larger Chinese diplomatic role in the Middle East. It will also depend on whether regional actors view China as willing and able to secure concrete concessions from Iran and the United States, rather than simply offering another forum for statements of principle.
As of April 4, 2026, the Security Council vote on Bahrain’s revised Hormuz draft has been postponed to next week, and the U.S. has not endorsed China and Pakistan’s five‑point plan. The coming days will test whether Beijing’s bid to cast itself as a crisis manager can shape the hard choices now confronting governments over energy security, maritime law and the future balance of power in the Gulf.
