Iran says Hormuz will reopen only after US accepts its demands, while Washington seeks unrestricted commercial shipping. (Donald Trump, Iran President Masoud Pezeshkian) Iran has made clear that a deal with Oman on a new shipping arrangement for the Strait of Hormuz will not, by itself, reopen the strategic waterway.

Tehran says the strait will reopen only after the United States accepts a broader set of Iranian conditions, while Washington has indicated that it is prepared to lift its blockade of Iranian ports once commercial shipping resumes without impediments. The competing positions have emerged as Iran and Oman move closer to an agreement on a new shipping protocol for the Strait of Hormuz, a narrow but critical maritime route through which a fifth of the world's oil and gas shipments passed before the conflict.

Iranian foreign minister Abbas Araghchi said Tehran and Muscat were "very close" to an agreement on a new arrangement for shipping through the strait. However, he made clear that the agreement with Oman would not be sufficient on its own to reopen the waterway.

The Islamic Revolutionary Guard Corps (IRGC) has also rejected suggestions that the reopening of the strait is simply a matter for the Iran-Oman negotiations. IRGC spokesperson Hossein Mohebbi said the reopening of the waterway was "contingent upon the United States accepting Iran's conditions and has no connection to the Iran-Oman negotiations."

He later said, " Whenever the United States accepts Iran’s conditions, the Strait of Hormuz will certainly be reopened," according to Iran's Tasnim news agency. The statements point to a much broader dispute than the technical question of how ships will navigate the strait.

At the centre of the disagreement are US military operations, sanctions, Iranian assets, compensation for wartime damage and control over shipping through one of the world's most important energy corridors. What Iran wants before reopening the straitIran's demands extend beyond an agreement with Oman on shipping arrangements.

1. An end to US threats against IranTehran wants Washington to stop threatening Iran and end what it sees as continued US pressure against the country.

For Iran, reopening the strait is therefore linked to the broader security situation. 2.

An end to US military actionIran wants the United States to halt military action against Iran and its regional allies. The demand comes after months of conflict involving US and Israeli attacks on Iran and Iranian retaliation against US interests and bases in the region.
