South-South cooperation has been a key pillar of the development agenda for more than two decades, becoming an important tool for mutual action and technological advancement among countries of the Global South. As participants sought to include Northern countries in these efforts, the concept of triangular cooperation emerged.
South-South triangular cooperation (SSTC) is a key approach in efforts to transform food systems. The July 2025 United Nations Food Systems Summit (UNFSS) stocktaking conference in Addis Ababa, Ethiopia, advocated SSTC as a tool for exchanging technologies and knowledge across the Global South, saying it can be a prime driver in development cooperation.
