The appointment of a civilian prime minister was a major prerequisite set by the West African regional economic bloc to remove the economic sanctions imposed on Mali following the junta's takeover of the country
Following the August 18 mutiny by Malian armed forces, ECOWAS 15 member states closed their borders with and stopped financial flows to the country, exerting pressure on the junta to hand back the government to civilians.
Ouane, 64, had served as Mali’s Permanent Representative to the United Nations from 1995 to 2002 and later as a diplomatic adviser to ECOWAS.
From 2004 to 2011, under former President Amadou Toumani Toure, he was minister of foreign affairs.
Mali’s new transitional president, former Defense Minister Bah Ndaw, appointed Ouane as prime minister on Sunday.
Ndaw, himself a retired colonel, was sworn into office as Mali's transitional president on Friday.
