The Group of Seven (G7, formerly G8) is a governmental forum of leading advanced economies in the world. It was originally formed by six leading industrial countries and subsequently extended with two additional members, one of which, Russia, is suspended. Since 2014, the G8 in effect comprises seven nations and the European Union as the eighth member.
