Mongolia has a 3485km- (2165 mile-) border with the Russian Federation in the north and a 4670km- (2902 mile-) border with China in the south. From north to south, it can be divided into four areas: mountain-forest steppe, mountain steppe and, in the extreme south, semi-desert and desert (the latter being about 3 per cent of the entire territory). The majority of the country has a high elevation, with the principal mountains concentrated in the west. The highest point is the peak of Tavan Bogd, in the Altai Mountains, at 4374m (14,350ft) high. The lowest point, Khukh Nuur lake, in the east, lies at 560m (1820ft). There are several hundred lakes in the country and numerous rivers, of which the Orkhon is the longest at 1124km (698 miles).

Republic. Declared independence from China in 1921. Head of State: President Nambaryn Enkhbayar since 2005. Head of Government: Prime Minister Miyeegombo Enkhbold since 2006. Recent history: The Mongolian Parliament chose the former mayor of Ulaanbaatar, Miyeegombo Enkhbold, as the new Prime Minister in the January 2006 elections. Mr Enkhbold was the widely expected choice, being the Mongolian People's Revolutionary Party (MPRP) candidate. Mongolia was plunged into crisis weeks before the election when the MPRP withdrew from the governing coalition, causing Prime Minister Tsakhia Elbegdorj to resign.
