Iran’s foreign minister Hossein Amir-Abdollahian during a visit to Oman has discussed the conflict in Yemen and the status of Iran’s nuclear talks with the West.

Iran’s official news agency IRNA reported Wednesday that Amir-Abdollahian met with Oman’s foreign minister Sayyid Badr Albusaidi and thanked him for mediation efforts by Sultan Haitham bin Tariq and the government of Oman “for their positive role” in JCPOA nuclear talks.

IRNA quoted Amir-Abdollahian as saying, “In addition to issues relating to expanding relations, I discussed regional issues with my Omani counterpart, as well as international problems, such as Palestine, Yemeni reconciliation and the situation in Sudan.”

IRNA commented that Oman has played an important role in Iran’s nuclear talks, “exchange of prisoners between Iran and the West”, and contacts between Iran and Saudi Arabia.

Oman has long played a mediating role between Tehran and Washington. First contacts in 2013 to launch nuclear talks were facilitated by Oman.

Meanwhile, Russian foreign minister Sergei Lavrov visiting the United Nations in New York, told reporters during a news conference on Tuesday that the revival of the JCPOA nuclear deal does not depend on Russia, China or Iran, indirectly accusing the United States for freezing talks.

The European Union presented a compromise agreement draft to Iran and Western powers last August, after 18 months of talks, but the United States accused Iran of stonewalling and presenting “extraneous” demands. In October, Washington said it is not focused on the talks any longer, demanding that Iran stop weapons supplies to Russia, among other things.
