Negotiations between Iran and the P5-1 then continued. A framework agreement was reached in Lausanne in April 2015. Intense marathon negotiations then continued, with the last meeting lasting 17 days in Vienna at the Coburg Palace.  Negotiations appeared to break up in several places, but negotiators reached an agreement.  When negotiators approached an agreement, U.S. Secretary of State John Kerry asked Iranian Foreign Minister Mohammad Javad Zarif to confirm directly that he was „entitled to reach an agreement, not only by the [Iranian] president, but also by the supreme leader?“  Zarif assured that he was.  In January 2016, the IAEA certified that Iran had complied with the provisional requirements of the nuclear agreement, including the offline inclusion of thousands of centrifuges, the futility of the Arak heavy water reactor and the sale of low-enriched surplus uranium to Russia. October 18, 2015: Iran informs the IAEA that it will temporarily implement its additional protocol and code 3.1 amended on the implementation date in its safeguards agreement. July 21, 2017: The JCPOA Joint Committee meets for the sixth time to discuss the implementation of the agreement. The United Against Nuclear Iran (UANI) group rejected the deal and pledged to spend more than $20 million on a „national television, radio, paper and digital campaign“ against the deal.   After UANI announced its opposition, the group`s president and co-founder, non-proliferation expert Gary Samore, announced that he had concluded „in the interest of the United States“ and supported the agreement.
 Samore resigned as president and was replaced by former Senator Joseph I. Lieberman.  Until August 20, UANI had issued its third national television ad against the agreement.  Trump ran for president and criticized the agreement, and the hope that the United States would pull out of the agreement discouraged trade and investment. Trade between the EU and Iran reached more than 20 billion euros a year before the U.S. withdrawal, but many large European companies have moved away from Iranian markets for fear of U.S. sanctions. 4 February 2006: An extraordinary meeting of the IAEA Governing Council to address Iran at the UN Security Council. The resolution considers it „necessary“ for Iran to suspend its enrichment activities, reconstitute the construction of the Arak heavy water reactor, ratify the additional protocol to its safeguards agreement and cooperate fully with the Authority. When announcing the withdrawal, Trump objected to the deal not attacking Iran`s ballistic program or its proxy wars in the region, saying the sunset provisions would allow Iran to pursue a bomb in the future. July 11, 2020: The Iranian Parliament approves a plan to end the implementation of the additional protocol to its safeguards agreement, in response to the resolution of the Governing Council of the International Atomic Energy Agency calling on Iran to investigate Iran`s possible undeclared nuclear activities in the past.
