The Group of Twenty (G20) was formed in 1999 after the Asian financial crisis as a forum for Finance Ministers and Central Bank Governors to discuss global economic and financial issues. It comprises 19 countries (Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Türkiye, United Kingdom, and the United States) and the European Union. The G20 members represent around 85% of the global GDP, over 75% of the global trade, and about two-thirds of the world population. G20 is a rotational form of Presidency so it does not have a permanent secretariat or staff. Due to the the global economic and financial crisis of 2007, and 2009, The G20 was upgraded to the level of Heads of State/Government. Since then G20 Leaders have met regularly, and it has become the premier forum for international economic cooperation. The forum discusses broad macroeconomic issues, as well as agendas in terms of trade, climate change, sustainable development, health, agriculture, energy, environment, climate change, and anti-corruption.
