Background: Long a province of China, Mongolia won its independence in 1921 with Soviet backing. A communist regime was installed in 1924. During the early 1990s, the ex-communist Mongolian People's Revolutionary Party (MPRP) gradually yielded its monopoly on power. In 1996, the Democratic Union Coalition (DUC) defeated the MPRP in a national election and has attempted to establish a number of reforms to modernize the economy. However, many former communists retain key posts and implementation has been difficult.
