Explanation:

The Intergovernmental Group of Twenty-Four on International Monetary Affairs and Development, or The Group of 24 (G-24) was established in 1971 as a chapter of the Group of 77 in order to help coordinate the positions of developing countries on international monetary and development finance issues, as well as and to ensure that their interests are adequately represented in negotiations on international monetary matters. Though originally named after the number of founding Member States, it now has 28 Members (plus China, which acts as a Special Invitee). Although the G-24 officially has 28 member countries, any member of the G-77 can join discussions.
