The Group of Twenty, widely known as the G20, stands as the premier intergovernmental forum for international economic cooperation. Representing the world's major developed and emerging economies, this collective carries immense weight, accounting for approximately 90% of global GDP, 80% of total international trade, and two-thirds of the world's population.

Historical Evolution and Structure

Established in 1999, the G20 initially functioned as a gathering for Finance Ministers and Central Bank Governors to navigate global financial crises. Recognizing the need for high-level political guidance, the forum transitioned to an annual summit of Heads of State in 2008, beginning with the inaugural Washington, D.C. summit. Notably, the G20 operates without a permanent secretariat or physical headquarters, with the presidency rotating annually to ensure regional representation.
