The French Far East Expeditionary Corps (Corps Expéditionnaire Français en Extrême-Orient (CEFEO)) was a colonial expeditionary force of the French Union Army that was initially formed in French Indochina in 1945 during the Pacific War (1941 – 1945). The CEFEO later fought and lost in the First Indochina War against the Việt Minh. It was largely made up of voluntarily-enlisted indigenous people from the colonial French Union or protectorate territories.
