The G20 is a forum of the world’s largest economies that meets to coordinate on major global issues, especially economic stability, trade, development, and climate-related challenges. It does not make binding laws, but its agreements and communiqués influence national policies and international cooperation.

What it does

  • Brings together 19 countries plus the European Union and African Union to discuss shared problems.
  • Focuses on the global economy, financial stability, sustainable growth, and debt and trade issues.
  • Also covers newer topics like climate change, health, digital governance, anti-corruption, and artificial intelligence.
  • Holds annual summits under a rotating presidency, with finance ministers, central bank governors, and working groups meeting throughout the year.

Why it matters

The G20 matters because its members represent about 85% of global GDP, over 75% of world trade, and roughly two-thirds of the world’s population. Even though it has no permanent secretariat or legal authority, it shapes the agenda for global economic cooperation.

If you want, I can also give you a very short 1-line version or a simple “G20 vs G7” explanation.
