In an increasingly uncertain world, the 2030 Agenda for Sustainable Development is a point of reference and a road map, and South-South and triangular cooperation have become ever more important for mobilizing additional resources for implementation of the Agenda, for increasing cooperation capacities and for providing flexible solutions to development challenges. The outcome of the second High-level United Nations Conference on South-South Cooperation invited interested developing countries to engage in consultations within the framework of the regional commissions, relevant intergovernmental forums on South-South and triangular cooperation or regional organizations, on non-binding voluntary methodologies for measuring and evaluating cooperation, building on existing experiences, taking into account the specificities and different modalities of South-South cooperation and respecting the diversity within South-South cooperation and within national approaches. This publication offers keys to understanding the value of South-South and triangular cooperation in the region, while providing data on the experiences of Latin American and Caribbean countries, as necessary inputs for advancing in the process of sharing and standardizing methodologies for measuring cooperation at the regional level.
