Russian President Vladimir Putin has signed a decree lifting the ban on supplying Iran with uranium enrichment equipment. It is linked to Russia importing enriched uranium from Iran, according to the official Russian government website.
The Russian President is visiting Tehran to take part in Gas Exporting Countries Forum summit, and is holding talks on Monday with Iranian President Hassan Rouhani and the country's Supreme Leader Ali Khamenei.
According to the document, the ban on supplying goods, materials and equipment no longer applies “to the exports of the enriched uranium from the Islamic Republic of Iran".
