“A range of unregulated issues remains…The main one is the unregulated issues of the likelihood and conditions of lifting the current arms embargo against Iran. The Russian Federation demands lifting [the arms embargo] first and foremost as a first step after concluding all the other arrangements,” Ryabkov said during an international committee hearing in the country’s upper house of parliament.
The official pointed out the UN Security Council's exclusive role in reinstating sanctions against Tehran.
Ryabkov added that the six world powers responsible for reaching the milestone framework deal with Iran two weeks ago are expected to meet again later in April.
The sides struck a preliminary deal on April 2 to reduce Iran's uranium enrichment capabilities by two-thirds over the next decade. The country is also required to allow strict outside monitoring until 2030.
A final deal ensuring Iran's inability to develop nuclear weapons within the framework of its civilian program is expected to be hammered out by June 30.
