EU 3 + 3 (also referred to as the E3+3, or P5+1 referring to the five permanent members of the UN Security Council plus Germany) refers to France, Germany, Russia, United Kingdom, United States, and People's Republic of China. It was coined when these states joined the diplomatic efforts with Iran in regards to its nuclear program.[2]
