International development cooperation is undergoing fundamental changes. New – or often re-emerging – actors have gained importance during the past two decades, and are increasingly challenging the traditional approach to development cooperation associated with the members of the Development Assistance Committee of the oecd. Their supposedly alternative paradigm, ‘South–South cooperation’ (ssc), has been recognised as an important cooperation modality, but faces contradictions that are not too different from those of its North–South counterpart. ssc providers are highly heterogeneous in terms of policies, institutional arrangements, and engagement with international forums and initiatives. This article contributes to current debates on ssc by mapping the diversity of its actors – based on illustrative case studies from the first and second ‘wave’ of providers – and by presenting and discussing some possible scenarios for the future of ssc within the international aid system.
