Muscat is the capital of Oman, on The Gulf of Oman beside the entrance to the strait of Hormuz. Its location places the city at the centre of Oman's maritime and diplomatic role in a route shared by Iranian and Omani waters.

Oman has long used Muscat as a venue for contact with Iran and the United States when direct talks are politically difficult. Reporting on 28 May described Oman as the broker of serious US-Iran back-channels since the 1981 hostage agreement.

That record gives Muscat enduring importance beyond any one negotiation. The city is a regional meeting point where maritime access, Gulf security and Iran-West diplomacy meet, even when the parties disagree over the terms of transit.

Key Issues

Hormuz transit

Muscat brokers the disputed passage

On 18 July, Muscat hosted Iranian talks focused solely on reopening the strait of Hormuz. The narrow agenda gave Oman a working diplomatic role without requiring agreement on the wider war.

That role rests on Oman's position beside the southern shipping channel. On 20 June, a US-led naval body cleared a route through Omani coastal waters after warning that standard lanes might contain mines; 55 ships carrying 17 million barrels used it that day. For Muscat, passage arrangements are therefore both a Mediation task and a direct test of its control over waters vital to regional trade.
