Presentation Abstract This paper is intended to examine South-South Triangular Cooperation (SSTrC) in Multi-Polar World in the 21st century in order to reflect on transforming Asia-Africa Relations. Although the Western (OECD-DAC) foreign aid architecture remains the leading role, it is no longer monopolistic in development assistance. Nowadays, South-South Cooperation is no longer a neglectable activity by traditional donors. Emerging Asian South-South Cooperation providers (or foreign aid donors) became influential in Africa. Triangular cooperation between influential development assistance providers and traditional donors has become more visible and potential in Africa. As the power balance in international relations and the global economy significantly changed, the practice of development assistance (or foreign aid) has gradually changed. The (re-)emerging global (non-OECD) partners (e.g., Brazil, China, India, and Indonesia) became more influential as development assistance providers. This paper examines South-South Triangular Cooperation (SSTrC) in collaboration with Northern OECD partners, which planned or operated its project in Africa to rethink South-South Cooperation in the changing structure of international order.
