The G20 or Group of 20 is an intergovernmental forum comprising 19 sovereign countries, the European Union (EU), and the African Union (AU) . It is a group of twenty of the worlds largest economies that meets regularly to coordinate global policy on trade, health, climate, and other issues. The G20 operates without a permanent secretariat or staff, and its chair rotates annually. The G20 summit is held annually, under the leadership of a rotating presidency, and it 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 Leaders' Summit is the climax of the G20 process and the work carried out over the year through Ministerial Meetings, Working Groups, and Engagement Groups. The 18th G20 Heads of State and Government Summit will take place in September 2023 in New Delhi, India, under the Indian Presidency, and it will focus on the theme, 'One Earth, One Family, One Future'. The summit will adopt a Leaders' Declaration 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.
