The world powers have voiced consent to the installation of new generation centrifuges for research purposes by Iran before declaring their Sunday night agreement on the start of the implementation of the Geneva interim nuclear deal on January 20, senior Iranian parliamentary officials announced on Monday. “The (use of) new generation of centrifuges for research purposes was the most important remaining issue in the talks between Iran and the G5+1 in recent months,” Chairman of the parliament’s National Security and Foreign Policy Commission Alaeddin Boroujerdi said in an interview with the parliament’s news website on Monday. “At last, the Group 5+1 accepted yesterday that Iran’s operating new generation of centrifuges for research does not run counter to the Geneva agreement,” he added. On Sunday, Iran and the six world powers agreed to start implementing the Geneva interim nuclear deal on January 20 and fulfill their undertakings simultaneously and on a single day. Senior negotiator and Deputy Foreign Minister Seyed Abbas Araqchi told the media on Sunday evening that "the (Geneva) deal will be put into effect on January 20”. Araqchi said his negotiations with EU foreign policy deputy chief Helga Schmidt continued until a few hours ago. "Finally we finalized the agreement between us and the Group 5+1 on how to implement the first step of the Joint Plan of Action, and the two sides came to a single interpretation on how to put the agreement into effect." He said a major part of the points pertaining to the implementation of the deal had been resolved during the experts meetings during the last several weeks, adding that he and Schmidt also worked out some solutions about the remaining points of difference. Araqchi said the solutions were to be approved by the capitals of all the seven countries. "And today we were informed that the 6 states (party to the talks with Iran) have voiced their consent to these solutions and accepted them. In Iran the relevant bodies also studied, assessed and agreed with these solutions and this agreement was declared during the contact between Ms. Schmidt and me," he added.
