Iran held talks with France on Wednesday in Geneva where Iranian Deputy Foreign Minister Abbas Araqchi said that the two sides had exchanged views to prepare the forthcoming round of negotiations next week in Vienna despite differences in opinion, Xinhua reported.
According to an official, the meeting of Nicolas Riviere, France's representative at the UN with Iran was "useful", without elaborating.
The meeting came ahead of the next round of nuclear talks between Iran and the P5+1 or the five permanent members of the UN Security Council - the US, China, Russia, France, Britain plus Germany - group scheduled for June 16-20 in Vienna.
Western leaders and Iran had set July 20 as a deadline to forge a final and comprehensive agreement.
However, following differences over a number of issues, the negotiations could extend for another six months.
