From the independence (1960), the relations between Zaïre and Belgium have known many difficulties. The most serious crisis took place from november 1988 to july 1989 (march 1990). A lot of questions were brought up: cooperation, debt, human rights... The agreement of Rabat provides for the future. Behind these events, it is possible to find some explanations of the crises: the past (relations colony-colonizing nation), the nature of power (differences between democracy and personal power) and the international surroundings.
