Analysis - The United Nations (UN) and African Union (AU) are quickly reaching a crossroads on how to collectively support multilateral peace operations. The issue is coming to a head because of rising levels of political violence across Africa, fragile peace agreements, a precarious macroeconomic environment, and a growing reliance on counter-terrorism efforts. Unless rectified, these differences could jeopardise the mainstay of the UN-AU partnership since 2002 and undo years of steady progress.
