Fonds d'Investissements pour le Developpement Économique et Social (FIDES) was the French infrastructure that delivered aid to its colonies, particularly in Africa.
It was widely criticized for having failed in many development programs. René Dumont (1962) writes of FIDES:
"within the framework of FIDES very large sums were granted to French-speaking Africa. In face of the immense needs, however, they seemed quite modest. The aid could in fact have been increased many times without a corresponding tax pressure, had France had the courage politically to decolonize more rapidly. Forty-six percent of the FIDES grants, particularly in the first four-year plan, were used to build roads, ports and airports. These were indispensable to open up the countries, but could have been achieved at less cost."
Paul Nugent (2004) "The consensus among historians is that FIDES amounted to much more than an ideological figleaf. It did channel substantial resources into the African colonies - initially ( as in the British case) into infrastructural development, but later also into industrial entreprises and agricultural projects."
