India has been a member of the G20 since its inception. The G20 (Group of Twenty) was established in September 1999, and India is one of the 19 member countries plus the European Union that make up the group. India is considered a founding member of the G20. India assumed the G20 Presidency on December 1, 2022, and hosted the G20 Leaders' Summit for the first time in 2023. The G20 presidency rotates annually among the members, and India's presidency year is from December 1, 2022, to November 30, 2023.
Thus, India became a G20 member from the group's formation in 1999.
