US warns against blocking the proposal

At the UN, US ambassador Mike Waltz, speaking alongside Gulf envoys, warned that countries opposing the resolution would be “setting a very dangerous precedent”. Secretary of State Marco Rubio also framed the vote as a test of the UN’s credibility on maritime security.

China, Russia likely to veto resolution

Diplomats familiar with the closed-door negotiations said China and Russia have strongly objected to the wording of the draft and are expected to veto it if it reaches a vote. According to reports, Beijing has raised concerns over references to Chapter VII of the UN Charter, which could open the door to coercive measures, while Moscow has pushed for major revisions or the complete withdrawal of the draft.

Iran rejects draft as ‘one-sided’

Iran has firmly rejected the proposal. Tehran’s representative to the UN, Amir Saeid Iravani, described the draft as “deeply flawed, one-sided, and politically motivated”. He also accused Washington of lacking the moral authority to present itself as a defender of maritime security while US forces continue operations targeting Iranian vessels in the Gulf.

Earlier Hormuz resolution also failed

The latest diplomatic effort comes just weeks after an earlier US-backed resolution on the Hormuz crisis failed at the Security Council following vetoes by China and Russia. Both countries had criticised that proposal as a potential pathway for authorising US military action against Iran.

Wider geopolitical impact looms

The dispute is also expected to have broader geopolitical consequences. A Chinese veto could complicate plans for US President Donald Trump’s upcoming visit to China, where the Iran conflict and disruptions to global oil shipping are likely to dominate discussions.
