A Kremlin decree published on Monday showed that Russia has eased an export ban on nuclear equipment and technology to Iran, reported Reuters.

The decree was issued on the same day as Putin arrived in Iran on an official visit, to attend the Gas Exporting Countries Forum (GECF).

The decree states that Russian firms are now authorised to export hardware and to provide financial and technical advice to help Iran with: modifying two cascades at its Fordow uranium enrichment plant; supporting Iranian efforts to export enriched uranium in exchange for raw uranium supplies; and helping Iran modernise its Arak heavy water reactor.

According to Russia Today the decree, signed by the Russian President, is linked to Russia importing enriched uranium from Iran.

The ban on supplying goods, materials and equipment no longer applies “to the exports of the enriched uranium from the Islamic Republic of Iran.”

Putin will also hold talks with Iranian President Hassan Rouhani and the country’s Supreme Leader Ali Khamenei. This is his first official trip to Iran since 2007.

Russian and Iranian leaders will discuss bilateral relations in trade and investment, nuclear energy, oil and gas, as well as exchanging views on international issues – the settlement of the conflict in Syria, the fight against terrorism and the implementation of the Joint Comprehensive Plan of Action (JCPOA) on Iran’s nuclear program.
