Oman’s Sultan Haitham bin Tariq is set to visit Iran for two days this week, according to Omani state media. The visit, which will begin on Sunday, comes after Saudi Arabia and Iran announced a rapprochement deal brokered by China in March. The Oman News Agency stated that the visit is in response to an invitation from the Iranian president and will focus on promoting cooperation between Oman and Iran in various areas. This visit follows a trip by Iranian President Ebrahim Raisi to Muscat last year, during which the two countries signed several trade agreements. Oman has close ties with Iran and played a mediating role in the lead-up to the 2015 nuclear deal between Tehran and Washington. Talks to restore the deal began last year after the US withdrew from it in 2018 and reimposed sanctions on Iran, prompting Tehran to scale back its commitments.
