Angola is a country in Southern Africa. It is the seventh-largest country in Africa. Since it gained independence from Portugal in 1975, the Civil War had begun between the People's Movement for the Liberation of Angola (MPLA)(Portuguese: "Movimento Popular de Libertação de Angola)" and the National Union for the Total Independence of Angola (UNITA). Although a peace treaty was concluded in May 1991, the National Union for the Total Independence of Angola (UNITA), which lost the referendum under the arbitration of the UN, caused the civil war again. In the process, the United Nations established United Nations Angola Verification Mission (UNAVEM) and the United Nations Observer Mission in Angola (MONUA). In February 1995, the United Nations asked South Korea to participate in United Nations Angola Verification Mission (UNAVEM). 201 people were dispatched on October 5, 1995, and 600 people were dispatched additionally by December 23, 1996.
