Abstract
Following the Berlin Conference, the territory which constitutes the present-day Democratic Republic of the Congo, had been ceded to King of the Belgians, Leopold II under the name of "Independent State of Congo ”. When this entity was annexed to Belgium in 1908, France made assert his right of pre-emption. However, she was unsuccessful. After the independence of the Belgian Congo, France adopted a ambivalent attitude, made up of sometimes divergent diplomatic strategies sometimes convergent. She spared no effort to display her ambitions sometimes trying to get ahead of Belgium in the name of the national interest.
