Mongolia (/mɒnˈɡoʊliə/ ( listen); Monggol Ulus in Mongolian; Монгол Улс
in Mongolian Cyrillic) is a landlocked unitary sovereign state in East Asia. Its area is roughly equivalent with the historical territory of Outer Mongolia, and that term is sometimes used to refer to the current state. It is sandwiched between China to the south and Russia to the north. Mongolia does not share a border with Kazakhstan, although only 37 kilometres (23 mi) separates them.
