The Group of Twenty (G20) is the main forum for international economic cooperation. It plays an important role in defining and strengthening global architecture and governance on all major international economic issues.

The G20 has annually rotating presidencies. Brasil will hold the G20 presidency from December 1, 2023, to November 30, 2024.
