The Group of Twenty (also known as the G-20 or G20) is an international forum for the governments and central bank governors from 20 major economies. The members, shown highlighted on the map at right, include 19 individual countries—Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the United Kingdom and the United States—along with the European Union (EU). The EU is represented by the European Commission and by the European Central Bank.
The G-20 was founded in 1999 with the aim of studying, reviewing, and promoting high-level discussion of policy issues pertaining to the promotion of international financial stability. It seeks to address issues that go beyond the responsibilities of any one organization. Collectively, the G-20 economies account for around 85% of the gross world product (GWP), 80% of world trade (or, if excluding EU intra-trade, 75%), and two-thirds of the world population.The G-20 heads of government or heads of state have periodically conferred at summits since their initial meeting in 2008.
With the G-20 growing in stature after the 2008 Washington summit, its leaders announced on 25 September 2009, that the group would replace the G8 as the main economic council of wealthy nations. Since its inception, the G-20's membership policies have been criticized by numerous intellectuals, and its summits have been a focus for major protests by anti-globalists, nationalists and others.
The heads of the G-20 nations met semi-annually at G-20 summits between 2008 and 2011. Since the November 2011 Cannes summit, all G-20 summits have been held annually. In December 2014, Turkey took over the presidency of the G-20 from Australia, and will host the group's 2015 summit in Antalya.
