Following a meeting between Iranian and American delegations in Geneva, the Iranian side reported that the talks seemed very constructive, adding that the interim agreement reached in November could be extended for another six months.

After five hours of talks, Abbas Araghchi told ISNA: “The discussions with the U.S. delegation were carried out in a positive and constructive atmosphere.

These direct talks between Iran and the U.S. are serving as a prelude to next week’s meeting between Iran and the world powers to further discuss the nuclear issues.”

Araghchi said that resolving the entire matter within 40 days is far too optimistic and there is a chance that the interim deal could be renewed for another six months.

A spokesman for the U.S. State Department also gave a positive assessment of the exchange but he added that more work must be done in some areas.

The last meeting between Iran and the 5+1 did not yield very notable results, but the Iranian foreign minister and the EU foreign policy chief later held a two-day unofficial meeting in Istanbul to get things back on track.
