French was a major language in diplomacy. Nowadays, this usage declines in particular within the intergovernmental organizations. Nevertheless, other dimensions must be taken into account in order to evaluate the relations between French and diplomacy like French-speaking institutions (the International Organization of the Francophonie and its operators), but also societal French-speaking actors. How these various francophonies perceive their role in a contemporary international system affected by structural change (redistribution of power with the “emergents”) or normative change (a trend of cultural homogenization vs the critic of westernization of the world) ? This article has two main objectives : to identify the diplomatic resources and actions adopted by the French-speaking institutional actors and to qualify the diplomatic role used by the F(f)rancophonies from the logic of the opening-up to the capacity building.
