Other parties that assisted the Paris meeting included the African Bloc of Guinea, Social Party of the Masses (Gabon), Republican Union of Côte des Somalis (Djibouti), Dahomeyan Democratic Rally and the Voltaic Democratic Movement.
Initially there was hope that the African Democratic Rally (RDA) would join the project and Sékou Touré had signed the appeal on behalf of RDA calling for the formation of the party, but Félix Houphouët-Boigny intervened to keep his party outside.
The African Independence Party (PAI) attended the Paris meeting, but declined to merge into PRA.
There it became the nucleus of Ivorian opposition, such as the National Liberation Committee of Côte d'Ivoire (CNLCI).
In Upper Volta the Voltaic Solidarity group (PSEMA, MDV and MPA) joined PRA.
