Originally, the world powers wanted to dismantle Arak because of the risk of proliferation. As part of an interim nuclear deal reached in 2013, Iran agreed not to put the reactor into service or to power it. 18-24 November 2014: Iran and the P5-1 meet in Vienna to continue negotiations for a comprehensive agreement. U.S. Secretary of State John Kerry will attend the November 20 talks. French Foreign Minister Fabiusu, British Foreign Minister Hammond and German Foreign Minister Steinmeier will participate in the talks from 20 to 22 November. Russian Foreign Minister Lavrov arrives on 23 November and Chinese Foreign Minister Wang arrives on 24 November. 19 October 2015: The first meeting of the Joint Commission will be held in Vienna. One of the objectives of the meeting is to create working groups that will be requested as part of the agreement, such as the Working Group on the Supply and Transformation of the Arak reactor. 4 February 2020: Josep Borrell Fontelles, EU High Representative for Foreign Affairs and Security Policy, reaffirmed at a press conference in Tehran the EU`s desire to preserve the JCPOA. He said the European parties to the agreement had agreed to “permanently postpone the dates and deadlines” of the dispute settlement mechanism to avoid the Security Council being referred. 26 June 2019: The Office of the Secretary-General of the United Nations informs the Security Council of its semi-annual report on the evaluation of the implementation of Resolution 2231.
The report deplores the US decision to extend non-proliferation declarations and states that the US measures are “contrary to the objectives” of the nuclear agreement. The report also deplores Iran`s announcement on 8 May that Tehran would no longer be bound by the limits of the agreement on heavy water and low-enriched uranium. The report notes that the Office of the Secretary-General examined several prohibited deliveries of conventional weapons and missiles and missile debris and found that, in several cases, these elements came from Iran, but were unable to determine whether the transfers took place before or after Resolution 2231 came into force in January 2016. July 8, 2019: Iran informs the IAEA that it has enriched uranium to “approximately 4.5 percent” uranium-235 at the Natanz fuel enrichment pilot plant. The agency released a report confirming that Iran has exceeded the 3.67% ceiling set by the nuclear enrichment agreement. In an interview with reporters, US President Donald Trump warned: “Iran should be careful.” September 8, 2015: Four other senators announce their support for the Iran nuclear deal, for a total of 42. This important step will prevent the Senate from reaching the 60-vote threshold needed to close the debate and pass a resolution of disapproval.
