The sub-regional quest for peace and security solutions is a major challenge that calls for political commitment and synergy of action. The natural potential of Central Africa has made it a vast field of multiform crises where the economic and ideological interests of the majority of the major powers clash. Therefore, the response can only be effective in a collective manner. This book presents collective security as an imperative for the survival, development and well-being of the populations of the subregion. It is part of the overview of the Republic of Congo's immense sub-regional work, within the framework of this collective vision of security, under the very high leadership of its successive leaders. This impetus has been consolidated under the High and Skilful Magisterium of His Excellency Denis SASSOU N'GUESSO, President of the Republic.
