Industrialization was introduced into Mongolia in the 1970s, with large investments from the Soviet Union, especially for mining and the processing of agricultural products. Through the 1970s and 1980s, the Mongolian government implemented an industrialization program that emphasized increasing investments and diversifying the country's exports. In the 1990s, because of prevailing conditions in the international market and the collapse of the traditional Soviet market, Mongolian industry underwent considerable restructuring. By 2001, Mongolia increasingly relied on export of its mineral resources, although there have been considerable efforts made to revive its manufacturing sector.
