US rewrites its Iran UN resolution—will China and Russia still veto it?

The United States has revised a proposed United Nations Security Council resolution targeting Iran’s activity in and around the Strait of Hormuz, specifically demanding that Tehran halt attacks and mining in the waterway. The update follows reporting that, despite Washington’s changes, Chinese and Russian diplomats are still expected to veto the draft. A Reuters account dated May 8 said the revisions are unlikely to prevent vetoes, with diplomats pointing to entrenched positions in the Council. On May 8, Russia’s Deputy Foreign Minister Alexander Alimov stated Moscow “doesn’t see any potential for this document,” signaling continued resistance to the U.S. text. The cluster also notes that a Chinese veto would carry political awkwardness ahead of U.S. President Donald Trump’s upcoming engagement cycle, raising the stakes for Washington’s diplomatic strategy. Strategically, this is a high-friction test of whether Washington can build a coalition for coercive pressure on Iran through the UN framework. The expected vetoes by China and Russia suggest that great-power rivalry is shaping the Council’s ability to respond to maritime security threats in a chokepoint that affects global energy flows. Iran benefits from the lack of consensus, because vetoes can delay or dilute collective enforcement measures while preserving room for continued pressure tactics at sea. The U.S. appears to be trying to regain momentum by adjusting the draft language, but the Russian position indicates that Moscow is not merely negotiating wording—it is rejecting the premise and leverage mechanism. China’s likely veto, as framed by diplomats, implies Beijing is balancing its own regional interests and relations with Tehran against alignment with U.S.-led escalation. Market implications center on risk premia tied to the Strait of Hormuz and the broader Middle East maritime corridor. Even without a formal UN enforcement outcome, the prospect of continued Iranian attacks and mining raises shipping and insurance costs, which typically transmits into higher crude oil volatility and tighter liquidity in energy-linked derivatives. The immediate direction is upward pressure on risk pricing for oil and refined products, with potential spillovers into LNG and shipping equities exposed to Middle East routes. Traders often translate such diplomatic deadlocks into “chokepoint risk” pricing, which can lift benchmarks like Brent and WTI relative to otherwise similar macro conditions. The magnitude is likely to be moderate but persistent, because the veto expectation reduces the probability of near-term multilateral de-escalation. What to watch next is whether the U.S. submits the revised text for a formal vote and whether any Council members signal a shift from the anticipated veto posture. Key indicators include additional diplomatic statements from Beijing and Moscow, changes in the draft’s operational language, and any evidence of coordination with regional maritime stakeholders. For escalation or de-escalation, the trigger is not only the UN vote outcome but also any reported incidents in the Strait of Hormuz—especially further mining activity or attacks that could force a security response. A timeline risk is that repeated vetoes can harden positions and encourage unilateral or coalition maritime measures outside the Council. Monitoring should therefore track both the diplomatic calendar in the Security Council and real-time shipping reports for the Strait of Hormuz over the coming days.

Geopolitical Implications

• 01

  Great-power rivalry is constraining UN-led collective action on Iran’s maritime threats.

• 02

  Veto expectations preserve Iran’s strategic flexibility while raising chokepoint risk.

• 03

  US diplomacy is being tested for coalition-building versus unilateral/coalition alternatives.

• 04

  Energy importers and insurers may price risk more than UN outcomes in the near term.

Key Signals

• —Whether the revised draft reaches a vote without further concessions.
• —Any shift in Chinese or Russian messaging from veto certainty to tactical delay.
• —Confirmed new incidents in the Strait of Hormuz, especially mining.
• —Movement in shipping insurance premiums and route changes for Hormuz corridors.
