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 80% of global economic output. The G20 meets annually to discuss important issues like economic growth, trade, and climate change, aiming to promote international financial stability. During these meetings, leaders, finance ministers, and central bank governors collaborate to address global challenges. The G20 also provides a platform for emerging economies, such as India and Brazil, to voice their concerns and influence global policies, making it a crucial part of international relations.
