Oman has been caught in geopolitical crossfire after Iran said it was coordinating with Muscat over the future management of the strait of Hormuz, including Tehran’s plans – opposed by the US – for fees to be paid by commercial shipping to a new Iranian government agency.
The Omani exclave of Musandam lies to the south of the contested waterway, which normally carries a fifth of the world’s seaborne oil traffic but has been blockaded for 10 weeks since since the US-Israeli attack on Iran in February.
The US has said repeatedly there can be no permanent solution to the blockade that involves the payment of a toll to the Iran, and claims that Oman holds a similar view.
Speaking in India on Friday, the Iranian foreign minister, Abbas Araghchi, defined the strait of Hormuz as an exclusively Omani-Iranian waterway. “The strait is located in the territorial waters of Iran and Oman,” he said. “There is no international waters in between.”
Araghchi added that Iran was coordinating with Oman about the future management of the strait. Oman has so far been silent about Iran’s plans to charge a fee and to demand details on the nationality of all ships passing through the the waterway.

A requirement that every ship set up a rial account to pay for services would also probably fall foul of UN sanctions prohibiting money being sent to the Islamic Revolutionary Guard Corps (IRGC).
A rival plan based on the freedom of navigation being prepared by France and UK has also been put to Oman, and has the support of most Gulf states.
British officials including the Foreign Office’s political director, Lord Llewellyn, has been recently been in Muscat, as has the secretary general of the International Maritime Organization, Arsenio Dominguez.
The legal rights of coastal states to impose tolls lies at the heart of the deadlock on how to reopen the strait and whether Iran’s proposed regime, by restricting freedom of navigation, is illegal and sets a precedent for other similar waterways.
Iran became a signatory to the UN convention on the law of the sea (Unclos) in 1982, very soon after the 1979 revolution, but never ratified the treaty. This means that from Iran’s perspective it is not bound by the treaty’s transit passage rules that underpin freedom of navigation, but instead by customary international law, including a more restrictive right of innocent passage.
Iran claims that even if it is bound by Unclos, the enhanced right of transit passage to ships of nations is conditional and passage specifically can be restricted in the event of any threat or use of force against “sovereignty, territorial integrity or political independence of the coastal states”.
Tehran said at the outset of the conflict that the southern shore of strait including the United Arab Emirates was used by the the US to arm American bases to attack Iran.
Iran hopes the Persian Gulf Strait Authority, government agency it established on 5 May, will become profitable revenue-generating stream. A grey area is whether Iran can only charge fees in return for providing services to ships, or whether in reality it would be compulsory to use those services, so in effect turning the service fee into a toll.
The PGSA says ships now have to register by email with its office to receive routing information and permission to pass the strait.
Payment would be required in Iran’s national currency. The fee is being set at roughly a dollar a barrel.

The US secretary of state, Marco Rubio, has also said China does not favour tolls.
The Chinese foreign ministry said it simply wanted the blockades to end and that the cause of the closure was the US-Israel war on Iran.
However, the IRGC briefed on Thursday that after talks with China’s ambassador to Iran a large group of Chinese oil tankers were being let through the strait by Tehran and that these ships had agreed to be subject to Iranian regime. The wording did not not reveal whether a fee was paid by China.
At the time the US imposed its blockade of Iranian ports, as a counter-measure to the Iran’s effective closure of the strait, Trump said: “No one who pays an illegal toll will have safe passage on the high seas.” That implied the US navy might feel entitled to block Chinese oil tankers if they paid a toll to Iran. However, it would be hard to gain evidence at the relevant moment whether a toll, or fee had been paid.
