While only one African member is formally part of the G20, Africa remains severely underrepresented in the most important multilateral group regarding global economic and financial cooperation. This policy brief argues that a greater degree of global integration and regional representation is key to ensuring the long-term legitimacy of the G20 itself. For this to be achieved, the G20 needs to become more inclusive, particularly by systematising its relationship with African multilateral institutions. Strengthening the relationship between the G20 and African multilateral institutions could be key to ensuring that a complex and diverse continent is better represented in global decision-making bodies. It also argues that the more systematic inclusion of African multilateral institutions should be followed by changes in the way the AU itself guarantees that its participation in G20 discussions will be more effective and meaningful.
