This publication analyses the state-of-the-art in international development cooperation, with a focus on South-South and triangular cooperation, based on a bibliographic and documentary review of more than 80 publications published between 2013 and 2022. The contents are organized under four headings: (i) development in transition as a foundation, (ii) multi-stakeholder environment: identification of key stakeholders, (iii) challenges and priorities in South-South and triangular cooperation, and (iv) towards the reconfiguration of South-South and triangular cooperation as a development tool: a collective approach. Through a review of concepts and proposals discussed in Latin America and the Caribbean over the last ten years, the author reflects on some of the challenges facing international development cooperation —and South-South and triangular cooperation in particular— in the context of the new development challenges shaped by the spirit of universality and indivisibility of the 2030 Agenda and its Sustainable Development Goals (SDGs).
