Iran says the experts of Iran and the group of six major world powers have reviewed proposals put forward by the both sides in their meeting in the Turkish city of Istanbul.
In a statement issued on Tuesday, Iran’s Supreme National Security Council said the Iranian and P5+1 (Britain, China, France, Russia, and the United States plus Germany) experts have discussed various aspects of proposals put forward by both sides.
According to the statement, the discussions revolved around proposals presented by Iran during the meeting in Moscow in June 2012, and offers given by the P5+1 during negotiations held in the Kazakh city of Almaty on February 26-27.
The statement added that results achieved in the two-day meeting will be presented at the upcoming round of talks in Almaty on April 5-6.
"The meeting also provided an opportunity for both (six-power) and Iranian experts to explore each other's positions on a number of technical subjects," Michael Mann, a spokesman for EU foreign policy chief Catherine Ashton, said in a statement earlier on Tuesday.
Iran and the P5+1 have both expressed optimism about the future of the talks. On February 28, Reuters quoted an unnamed Western diplomat as saying that, "This was more constructive and more positive than previous meetings because they were really focusing on the proposal on the table."
In an interview with Austrian broadcaster ORF on March 1, Iran’s Foreign Minister Ali Akbar Salehi described the latest round of the talks as a “milestone” and a “turning point in the negotiations.”
The United States, Israel, and some of their allies have repeatedly accused Iran of pursuing non-civilian objectives in its nuclear energy program, with US and EU using this pretext to impose several rounds of illegal unilateral sanctions against Tehran.
Tehran refutes the allegation, maintaining that as a signatory of the Nuclear Non-Proliferation Treaty and a member of the International Atomic Energy Agency, it has the right to enrich uranium for peaceful purposes.
