Top negotiators from Iran and the six world powers ended their fourth and last round of talks at the UN offices in Geneva on Wednesday afternoon.
The fourth session which was attended by Iran`s Foreign Minister Mohammad Javad Zarif and EU foreign policy chief Catherine Ashton, who presides over the delegations of the six world powers in the talks with Iran, lasted only for a few minutes.
The seven sides had two sessions of talks on Tuesday morning and afternoon and two more meetings on Wednesday.
The first session started by the remarks of Iranian Foreign Minister Mohammad Javad Zarif, who presented Iran`s new three-staged package of proposals to the delegations of the six world powers.
Zarif and EU foreign policy chief Catherine Ashton, who presides the delegations of the six world powers in the talks with Iran, did not take part in the second and third sessions.
In the first session, Zarif said he would come back to take the lead of the Iranian team when his counterparts from the group of P5+1 (the five permanent UN Security Council members - the US, Britain, China, Russia and France - plus Germany) take part in the talks.
Yet, the fourth session was attended by both Zarif and Ashton.
The third round of talks a little after midday (Geneva time) was postponed for two hours after the delegations of the six world powers demanded for a delay to discuss Iran`s proposals in an internal meeting.
During their third meeting, which lasted for two hours on Wednesday afternoon, the negotiating teams of Iran and the P5+1 decided to continue the talks over the former`s nuclear issue on November 7 and 8.
The two sides decided to have their experts committees to be comprised of their nuclear and sanctions experts in the November meeting.
During the meetings, Iran presented a three-staged package of proposals to the opposite side which includes confidence-building measures for a settlement of the Iran-West nuclear standoff.
The Iranian and P5+1 officials also held some bilateral meetings on the sidelines of their multilateral talks, which included two meetings between Zarif and Ashton, a meeting between Iranian Deputy Foreign Minister Seyed Abbas Araqchi and Head of the US delegation Windy Sherman and also two meetings between Araqchi and his Russian counterpart Sergei Ryabkov.
Both Iran and the world powers have described the meetings on Wewdnesday as "positive" and "constructive".
"Mr. Zarif had a PowerPoint presentation of the plan in details, the generalities of the plan were discussed in the morning session and the details will be studied by (the two sides) political directors in the afternoon," Araqchi said after the end of the morning session of the talks.
Araqchi, who is also the spokesman and the number two person in the Iranian team, told reporters that "the negotiations were held in a highly positive atmosphere and the two sides were serious when speaking of their issues".
He said that the world powers have welcomed the general points of Tehran`s proposals on the settlement of the country`s nuclear standoff with the West, adding that Iran is seeking to encourage the opposite side to pursue a common goal for the negotiations.
"The Group of P5+1 member states welcomed the generalities of Irans plan," Araqchi told reporters before the start of the Tuesday afternoon meeting.
And then after the second session on Tuesday, a diplomatic source present in the negotiations said the delegations of the six world powers have shown a positive and constructive reaction to the details of Tehran`s proposals.
"The atmosphere dominating the meeting was positive and constructive and the negotiations will continue tomorrow morning," a diplomatic source close to the Iranian delegation told FNA after the end of the second session of the Tuesday talks between Tehran and the P5+1.
"Both sides (Iran and the six world powers) showed a serious attitude during the meeting and negotiations and several questions were asked and answered face-to-face," the source added.
The diplomat said the two sides discussed "the details of Iran`s three-staged proposal" and "the Iranian side elaborated on its plan".
