The G8 reverted to its original G7 format in 2014 when, in the wake of Crimea’s reunification with Russia, the leaders of the Group of Seven industrialized nations decided to stay away from their planned summit in Sochi and, instead, met in Brussels without Russia.
Russian Foreign Minister Sergei Lavrov then said that no one had actually excluded Russia from the G8.
“The G8 is an informal club, no one gives out membership cards and no one can expel members”, he added.
The G7 comprises leaders of Canada, France, Germany, Italy, Japan, Britain and the United States.
Russia was suspended from being a part of the G8 group last year amid tensions over Crimea.
In March 2014, Russia and Crimea reunified following a referendum, where 96 percent of the voters backed reunification.
