The G20, or Group of Twenty, is an international forum that brings together the world's major economies. It includes 19 countries and the European Union, representing about 85% of global GDP and two-thirds of the world's population. The group meets annually to discuss and coordinate economic policies, addressing issues like trade, climate change, and sustainable development. Established in 1999, the G20 was initially a response to financial crises, aiming to promote international financial stability. Over the years, its agenda has expanded to include a wide range of global challenges, making it a key platform for international cooperation and dialogue among both developed and emerging economies.
