In April this year, the Joint Committee overseeing the nuclear deal started negotiations in Vienna with the participation of Iran, Russia, China, France, the UK, Germany and the EU aimed at bringing Iran and the US back into compliance with the 2015 Iran nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA).

The latest round of negotiations took place on June 20, but the parties have not yet set a time to conduct further negotiations.
