Mongolia (/mɒŋˈɡoʊliə/ ) is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of 1,564,116 square kilometres (603,909 square miles), with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. Approximately 30% of the population is nomadic or semi-nomadic; horse culture remains integral. Buddhism is the majority religion, with the nonreligious being the second-largest group. Islam is the second-largest religion, concentrated among ethnic Kazakhs. Most citizens are ethnic Mongols, with roughly 5% of the population being Kazakhs, Tuvans, and other minorities, who are especially concentrated in the west. Mongolia is a member of the United Nations, Asia Cooperation Dialogue, G77, Asian Infrastructure Investment Bank, Non-Aligned Movement and a NATO global partner. Mongolia joined the World Trade Organization in 1997 and seeks to expand its participation in regional economic and trade groups. (Source: Wikipedia.org, CC BY-SA)
