In a context marked by the multiplicity of Regional Economic Communities in Central Africa and its corollary, the loss of resources, this book deals with the harmonization of CEMAC and ECCAS integration policies and programs in order to achieve a rationalization of these Communities. It is therefore a question of understanding in a substantial manner the foundations of this process of bringing the Communities closer together. Following this, it is a question of evoking the priority domains to be harmonized. Thus, the present work questions the balance and the perspectives of this process.Clearly, the harmonization of Regional Economic Communities in Central Africa is underway. However, there are still obstacles to its development, hence the proposals to revitalize this important project, both for the Central African States and for the continent in general, since it is a step towards the advent of a United States of Africa.
