South-South Cooperation (CSS) consists of the exchange of resources or experiences between two developing countries. In this exchange there are no conditions and the speech is performed on equal terms.
Costs are accepted for both parts, but it doesn´t mean that both of them have equivalent shares. Countries divide their roles into donor roles (the one who provides financial, technical and human resources) and recipient roles.
