Least developed countries
The least developed countries (LDCs) are a list of developing countries that, according to the United Nations, exhibit the lowest indicators of socioeconomic development, with the lowest Human Development Index ratings of all countries in the world. The concept of LDCs originated in the late 1960s and the first group of LDCs was listed by the UN in its resolution 2768 (XXVI) of 18 November 1971. A country is classified among the Least Developed Countries if it meets three criteria: As of December 2020, 46 countries are classified as LDC, while six have been upgraded between 1994  and 2020. The World Trade Organization (WTO) recognizes the UN list and says that "Measures taken in the framework of the WTO can help LDCs increase their exports to other WTO members and attract investment. In many developing countries, pro-market reforms have encouraged faster growth, diversification of exports, and more effective participation in the multilateral trading system." Overview. LDC criteria are reviewed every three years by the Committee for Development Policy (CDP) of the UN Economic and Social Council (ECOSOC). Countries may be removed from the LDC classification when indicators exceed these criteria in two consecutive triennial reviews. The  United Nations Office of the High Representative for the Least Developed Countries, Landlocked Developing Countries and Small Island Developing States (UN-OHRLLS) coordinates UN support and provides advocacy services for Least Developed Countries. The classification () applies to 46 countries. At the UN's fourth conference on LDCs, which was held in May 2011, delegates endorsed a goal targeting the promotion of at least half the current LDC countries within the next ten years. As of 2018, 10 or more countries were expected to be upgraded by 2024, with Bangladesh and Djibouti already satisfying all criteria in 2018. There is one  country which presently meets the criteria and two countries which previously met the criteria for LDC status, but declined to be included in the index, questioning the validity or accuracy of the CDP's data: Ghana (no longer meets criteria as of 1994), Papua New Guinea (no longer meets criteria as of 2009), and Zimbabwe. Usage and abbreviations. Least developed countries can be distinguished from developing countries, "less developed countries", "lesser developed countries", or other terms for countries in the so-called Third World. Although many contemporary scholars argue that "Third World" is outdated, irrelevant or inaccurate, others may use  the term "Fourth World" in reference to least developed countries (although Fourth World is also used to refer to stateless ethnic groups). The term "less economically developed country" (LEDC) is also used today. However, in order to avoid confusion between "least developed country" and or LEDC "less economically developed country" (which may both be abbreviated as LDC), and to avoid confusion with landlocked developing country (which can be abbreviated as LLDC), "developing country" is generally used in preference to "less-developed country". During a United Nations review in 2018, the UN defined LDCs as countries meeting three criteria, one of  which was a three-year average estimate of gross national income (GNI) per capita of less than US$1,025. Countries with populations over 75 million are excluded. Declassification. The three criteria (human assets, economic vulnerability and gross national income per capita) are assessed by the Committee for Development Policy every three years. Countries must meet two of the three criteria at two consecutive triennial reviews to be considered for graduation. The Committee for Development Policy sends its recommendations for endorsement to the Economic and Social Council (ECOSOC). Since the LDC category was initiated, six countries have graduated to "developing country  status. The first country to graduate from LDC status was Botswana in 1994. The second country was Cape Verde in 2007. Maldives graduated to developing country" status on 1 January 2011, Samoa graduated in 2014, Equatorial Guinea in 2017, and Vanuatu in December 2020. Bhutan will graduate in 2023, and São Tomé and Príncipe and Solomon Islands will leave the category in 2024. Nepal was selected to be graduated to developing countries on 2018. However, the authorities of Nepal requested to postpone it till 2021. Angola was expected to graduate in 2021, but the preparatory period was extended by three  years because of the economic difficulties of the country and its dependence on commodities. Bangladesh met the criteria for the first time in 2018 and again in 2021 for the second time. The country is scheduled to officially graduate from LDC status in November 2026, two years after it was supposed to, because of the COVID-19 pandemic. Laos and Nepal will also graduate in November 2026. UN conferences. There have been four United Nations conferences on LDCs, held every ten years. The first two were in Paris, in 1981 and 1991; the third was in Brussels in 2001. The Fourth  UN Conference on Least Developed Countries (LDC-IV) was held in Istanbul, Turkey, 9–13 May 2011. It was attended by Ban Ki-Moon, the head of the UN, and close to 50 prime ministers and heads of state. The conference endorsed the goal of raising half the existing Least developed countries out of the LDC category by 2022. As with the Seoul Development Consensus drawn up in 2010, there was a strong emphasis on boosting productive capability and physical infrastructure, with several NGOs not pleased with the emphasis placed on the private sector. Trade. Issues surrounding global trade regulations and  LDCs have gained a lot of media and policy attention thanks to the recently collapsed Doha Round of World Trade Organization (WTO) negotiations being termed a development round. During the WTO's Hong Kong Ministerial, it was agreed that LDCs could see 100 percent duty-free, quota-free access to U.S. markets if the round were completed. But analysis of the deal by NGOs found that the text of the proposed LDC deal had substantial loopholes that might make the offer less than the full 100 percent access, and could even erase some current duty-free access of LDCs to  rich country markets. Dissatisfaction with these loopholes led some economists to call for a reworking of the Hong Kong deal. Dr. Chiedu Osakwe, as of 2001 the Director, Technical Cooperation Division at the Secretariat of the WTO, and adviser to the Director-General on developing country matters, was appointed as the WTO Special Coordinator for the Least Developed Countries beginning in 1999. He worked closely with the five other agencies that together with the WTO constitute the Integrated Framework of action for the Least Developed Countries. They addressed issues of market access, special and differential treatment provisions for developing countries , participation of developing countries in the multilateral trading system, and development questions, especially the interests of developing countries in competition policy. At the 28th G8 summit in Kananaskis, Alberta, Canadian Prime Minister Jean Chrétien proposed and carried the Market Access Initiative, so that the then 48 LDCs could profit from "trade-not-aid". Additionally, the United Nations Sustainable Development Goal 14 advocates for an effective special and differential treatment of LDCs as integral parts of WTO fisheries subsidies negotiation. List. The list of "least developed countries" according to the United Nations with some that are categorised into the landlocked developing  countries and the Small Island Developing States: There are 33 countries that are classified as least developed countries in Africa, nine in Asia, three in Oceania, and one in the Americas.
