The Group of Twenty 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, United Kingdom, United States—and the European Union. The EU is represented by the European Commission and by the European Central Bank. The G-20 is the latest in a series of initiatives aimed at international coordination of economic policy, which have been prominent since the efforts during World War II to create some form of international or global economic governance, including through the "Bretton Woods twins", the International Monetary Fund and the World Bank, and what is now the World Trade Organization. Collectively, the G-20 economies account for around 85% of the gross world product, 80% of world trade, 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.
