Oman’s foreign minister arrived in Tehran on Wednesday for talks with his Iranian counterpart, state media reported, as nuclear talks between Iran and world powers continue in Vienna.
Iranian Foreign Minister Hossein Amirabdollahian welcomed Sayyid Badr Albusaidi upon his arrival, with the visit scheduled to focus on bilateral and international affairs, the IRNA news agency said.
Oman has often acted as a go-between to help facilitate back-door diplomacy between the U.S. and Iran, sometimes involving the release of prisoners.
Negotiations in Vienna aim to restore a 2015 nuclear deal that saw Tehran drastically limit its enrichment of uranium in exchange for the lifting of economic sanctions.
The diplomatic visit raised speculation that Oman may get involved as an intermediary in the ongoing nuclear talks, or deliver a U.S. message to Iran.
The U.S. has participated indirectly in the ongoing talks because it withdrew from the accord in 2018 under then-President Donald Trump. President Joe Biden has signaled that he wants to rejoin the deal. Trump later re-imposed crushing sanctions on Iran.
