G8 and G20 were both formed from the G7. The G7 was a coalition of seven nations formed to fight the oil embargo imposed by the Arabs on some countries of this coalition. Italy, Japan, France, Britain, Canada, the United States, and Germany were members of the G7. However, the name of the coalition was changed to the G8 to accommodate Russia. Russia would have been a member of this coalition when it was created in 1975; however, the alleged involvement of the U.S.S.R in support of the Arab nations stopped Russia. The G8 has been a powerful coalition where vital political and economic policies and decisions are made. However, in 1999, this coalition was expanded to accommodate other countries such as China, Brazil, Saudi Arabia, the European Union, Turkey, Australia, India, the Republic of Korea, South Africa, Indonesia, the United Kingdom, and Argentina. This development brought about the renaming of the G8 to the G20.
