South–South cooperation is a term historically used by policymakers and academics to describe the exchange of resources, technology, and knowledge between developing countries, also known as countries of the Global South. The Global South is making increasingly significant contributions to global development. The economic and geopolitical relevance of many countries has grown. In the past, south-south cooperation focused on sharing knowledge and building capacities, but the countries of the Global South and new financial institutions have recently also become increasingly active in development finance.
