Multi-stakeholder partnerships are of great relevance in international development cooperation and foreign aid. Data is also critical in supporting this field, but it is difficult to obtain updated information about G20 members’ respective actions and budgets, mainly due to insufficient institutionalisation within multilateral organisations and low levels of data systematisation and transparency at the national level. In view of this, I assess updated information about G20 members’ policy priorities, and present a brief account of the scenario, including how the OECD’s Official Development Assistance and South-South Cooperation contribute to Sustainable Development Goal #17, particularly against the critical juncture of the COVID-19 pandemic. Finally, I spell out key challenges for G20 members as foreign aid providers and SSC partners, and propose the creation of a Working Group on International Development Cooperation and Foreign Aid (WGIDCFA) within the T20.
