Larijani pointed to the many ups and downs in the nuclear talks between Iran and the Group 5+1 (the five permanent UN Security Council members plus Germany) and said, "The recent talks between Irans team of negotiators and the Group 5+1 showed that Irans nuclear issue can be solved."
Breen, for his part, voiced optimism about the future of Iran-G5+1 negotiations, and said, "Since the very beginning, the Irish government has laid emphasis on the need for dialogue and political consultations for resolving Irans nuclear issue."
A delegation from the Republic of Irelands parliament led by Breen arrived in Tehran on Friday morning to discuss ways to expand bilateral ties.
On Saturday, Iranian Deputy Foreign Minister and senior negotiator Seyed Abbas Araqchi said that his recent talks with EU Deputy Foreign Policy Chief Helga Schmidt were held in a "serious" atmosphere, adding that the two sides reached an agreement on the date for starting implementation of the Geneva deal.
"The negotiations were held in an atmosphere of understanding and were highly serious," Araqchi told FNA on Saturday after meeting Schmidt in Geneva on Thursday and Friday.
He noted that Iran and the world powers have not yet reached an agreement on their remaining differences, and said some solutions were proposed by the two sides which need to be decided by the capitals.
"Everything depends on the final decision of the capitals and we hope that it (the results) will be announced within the next one or two days," Araqchi said.
Asked if any date has been agreed by him and Schmidt to start implementation of the Geneva agreement, he said, "The proposed date for the implementation of the first step of the Geneva agreement was agreed but its announcement depends on the capitals agreement with the proposed solutions."
"If the solutions are agreed upon, the proposed date will be finalized and declared," Araqchi underlined.
On November 24, Iran and the Group 5+1 (the US, Russia, China, Britain and France plus Germany) sealed a six-month Joint Plan of Action to lay the groundwork for the full resolution of the Wests decade-old dispute with Iran over its nuclear energy program. In exchange for Tehrans confidence-building bid to limit certain aspects of its nuclear activities, the Sextet of world powers agreed to lift some of the existing sanctions against Tehran and continue talks with the country to settle all problems between the two sides.
Iran and the six world powers ended a third round of expert-level talks in Geneva, Switzerland, early January in a bid to devise mechanisms to implement the interim nuclear deal struck in November.
The foreign ministry officials in Tehran announced last Friday that the timeline for the implementation of the November nuclear deal between Iran and the six world powers would be set after the meeting between senior Iranian and EU negotiators.
"The exact date for the implementation of the Geneva agreement will be after an upcoming meeting between Schmidt and Araqchi," Irans Deputy Foreign Minister and senior negotiator in talks with the world powers Majid Takht Ravanchi said at the time.
In relevant remarks on Wednesday, Iranian Foreign Minister Mohammad Javad Zarif underlined the countrys commitment to its undertakings based on the Geneva deal, and said Tehran is serious about implementing the Joint Plan of Action.
"We are much serious about continuing the path based on the Joint Plan of Action agreed by the ministers (of Iran and the Group 5+1) in Geneva and we believe that progress and entering the next difficult stage, or in other words negotiation and reaching a comprehensive solution, is completely possible through the other sides commitment to the Geneva agreement," Zarif said on his Facebook status on Wednesday.
"The nuclear negotiations are underway seriously and with strong political will; the expert delegations of Iran and the G5+1 have had tens of hours of intensive negotiations and reached positive results," he added.
