Finally, the JCPOA is establishing a supply channel overseen by a joint commission that will allow Iran to retain the materials needed to operate its nuclear facilities, in accordance with the guidelines of international nuclear supply systems such as the Nuclear Suppliers Group (NSG).  20-24 November 2013: Iran and the P5-1 meet in Geneva to continue negotiations. On 23 November, the foreign ministers of the P5-1 will participate in the negotiations. On 24 November, Iranian Minister Javad Zarif and Catherine Ashton, head of the P5-1 negotiating team, signed an agreement called the Joint Plan of Action. It defines specific measures and a broad framework for each side, as part of a six-month agreement of the first phase, to guide negotiations for a comprehensive solution. On July 28, 2015, Michigan Democrat Sander M. Levin announced in a lengthy statement that he would support the JCPOA, Michigan Democratic Congressman Sander M. Levin said that “the agreement is the best way” to prevent Iran from obtaining a nuclear weapon and that a rejection of the agreement would result in the international sanctions regime “rapidly disintegrating.” , because “sanctions would probably not even be pursued by our closest allies, and the United States would be isolated if it tried to impose our unilateral sanctions on Iran`s banking and oil sectors.”    In February 2006, Tehran ended the voluntary implementation of the additional protocol and resumed enrichment in Natanz. The IAEA Governing Council then voted in favour of notifying the UN Security Council of the Iranian case.
On 15 March, the UNSC issued a statement from the President calling on Iran to cooperate with the IAEA.  Iranian President Mahmoud Ahmadinejad responded with a speech in April on Iran`s possession of a second uranium enrichment plant with P-2 centrifuges.  In June, the EU-3, along with the United States, China and Russia (P5-1), proposed to Tehran to provide Tehran with advanced civilian nuclear technology if Iran suspended its enrichment activities and resumed the implementation of the additional protocol.  Iran responded to this proposal in a letter to President George W. Bush, who made only a brief reference to the nuclear issue and did not respond to requests from the international community.
