The first day of the new round of nuclear talks between Iran and the 5+1 ended in Vienna on Tuesday March 18 with all sides sounding positive notes.

Michel Mann, the spokesman for EU foreign policy chief Catherine Ashton, described today’s talks as “constructive” and “useful”.

The talks began with discussions between Ashton and Iranian Foreign Minister Mohammad Javad Zarif.

Later, Abbas Araghchi, the Iranian deputy foreign minister, and Helga Schmid, Ashton’s deputy, discussed details of the proposed plans.

The parties reached an interim deal last November in Geneva and are set to reach a comprehensive final deal within six months of the implementation of the Geneva agreement.

The plan was implemented in January, when sanctions against Iran were eased in exchange for a series of concessions by Iran regarding its nuclear program.
