The Group of 77 (G-77) was established on 15 June 1964 by seventy-seven developing countries signatories of the “Joint Declaration of the Seventy-Seven Developing Countries” issued at the end of the first session of the United Nations Conference on Trade and Development (UNCTAD) in Geneva. Although the members of the G-77 have increased to 134 countries, the original name was retained due to its historic significance. Source: g77.org
