The G20 is an intergovernmental forum comprising 19 sovereign countries, the European Union (EU), and the African Union (AU) . The G20 operates without a permanent secretariat or staff, and the groups chair rotates annually among the members and is selected from a different regional grouping of countries. The G20 initially focused largely on broad macroeconomic issues, but it has since expanded its agenda to include trade, sustainable development, health, agriculture, energy, environment, climate change, and anti-corruption. The G20 Summit is held annually, under the leadership of a rotating Presidency.

The 18th G20 Summit in New Delhi will be held on September 9 - 10, 2023, and will be a culmination of all the G20 processes and meetings held throughout the year among ministers, senior officials, and civil societies. A G20 Leaders’ Declaration will be adopted at the conclusion of the New Delhi Summit, stating Leaders’ commitment towards the priorities discussed and agreed upon during the respective ministerial and working group meetings.

Recently, there have been discussions about the G20 becoming the G21, with the African Union joining as a permanent member. This would be a powerful acknowledgement of a continent of 1 billion people. Prime Minister Narendra Modi has been pushing for the African Union to join the G20.
