The Iran nuclear deal framework was a preliminary framework agreement reached in 2015 between the Islamic Republic of Iran and a group of world powers: the P5+1 (the permanent members of the United Nations Security Council—the United States, the United Kingdom, Russia, France, and China—plus Germany) and the European Union. Based on the April 2015 Iran nuclear deal framework, the Joint Comprehensive Plan of Action between Iran and the P5+1 and EU was announced on July 14, 2015 in Vienna.
