Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al-Thani visited Muscat on Wednesday for talks with Oman on initiating negotiations involving Iran, Iraq and Gulf Arab states on the Strait of Hormuz, a diplomat briefed on the talks told Reuters.

​The discussions are separate from US-Iran peace talks and de-mining arrangements. Gulf states are expected ​to push for no transit fees, while Iran could propose environmental, navigation and ⁠security fees, the diplomat said.

The Strait of Hormuz, a vital route for roughly a fifth of ​global oil and liquefied natural gas supplies, has been heavily disrupted since the United States and Israel launched ​a war against Iran on February 28, curbing commercial shipping and rattling global energy markets.

The move appears to implement a provision of the memorandum of understanding signed last week that calls for Iran to hold talks with Oman ​and other Gulf states and Iraq on the future management of navigation and maritime services in the ​strait.

The diplomat added that Pakistan was the proposed mediator for these talks.

Separately, there are plans for regional ‌reconciliation ⁠talks to be held in Riyadh between Iran, Gulf Arab states and possibly other regional countries, he said.

Oman announces temporary routes

Earlier on Wednesday, Oman announced two temporary routes north and south of the existing shipping lane in the strait to facilitate the safe passage of vessels departing the region in coordination ​with the International Maritime ​Organisation (IMO).

Under a phased ⁠plan developed by the IMO in coordination with Omani authorities, vessels will be grouped and contacted individually with instructions on when they may depart and which ​route they should follow.

Oman said shipowners and masters remained responsible for ​conducting independent risk ⁠assessments before voyages. Vessels were instructed to keep their Automatic Identification System activated during transit and to report any navigational hazards to the Oman Maritime Security Centre.

Oman’s statement said that no tolls would be imposed ⁠on vessels ​transiting the Strait of Hormuz, in line with the outcome of ​recent talks between the United States and Iran.

Iran and Oman began discussions on the future administration of navigation and maritime services in ​the waterway on Tuesday.
