Iran has been engaged in negotiations to revive the accord formally known as the Joint Comprehensive Plan of Action (JCPOA) with Britain, China, France, Germany and Russia directly, and the United States indirectly since April 2021.

European Union diplomat Enrique Mora, who coordinates talks between Iran and the US, arrived in Tehran late Saturday and on Sunday met Iran’s chief negotiator Ali Bagheri, state news agency IRNA reported.
