based on "Gentlemen’s Agreements" agreed upon by the United States and the Soviet Union regarding the distribution of seats in United Nations bodies. Reform Following a wave of decolonization, there were multiple admissions into the United Nations from African, Asian and Pacific states. After the Bandung Conference in 1955, there was increasing solidarity among post-colonial states which led to pressure being put on the United Nations for increased representation of these states. This pressure led to the passage of Resolution 1192 (XII) of 12 December 1957, which established a formal pattern for distribution of seats on the General Committee. This was followed on 17 December 1963 by Resolutions 1990 (XVIII) and 1991 (XVIII). These resolutions further outlined the distribution of seats on the General Committee, but also outlined how seats would be geographically distributed on the Economic and Social and Security Councils. The resolutions outlined the regions as follow: African and Asian states Latin American states Eastern European states Western Europe and Other states On 20 December 1971 Resolution 2847 (XXVI) formally set up the present distribution system that is in place for the Economic and Social Council. It also split the African and Asian states region into two separate regions, one for Asia and one for Africa. Finally, on 19 December 1978 Resolution 33/138 was passed by the General Assembly. This resolution called for equitable geographic distribution of the presidency and vice-presidencies of the General Assembly, as well as of the chairmanship of the seven main committees. Present The most recent change to the regional grouping system was in 2011, when the Asia Group was renamed the Group of Asia and the Pacific Small Island Developing States, also Asia and the Pacific Group or Asia-Pacific Group, in order to recognise the growing role Pacific island nations play in the United Nations System. As of 2019, Kiribati is the only United Nations Member State that has never joined one of the regional groups. Overview Apart from allowing member states with related international interests to liaise, discuss and coordinate their voting and other activities at the United Nations, the main function of the regional groups is to distribute membership quotas in United Nations bodies and leadership positions. According to convention, the non-permanent membership seats of the United Nations Security Council is apportioned between regional groups according to a set formula.
