The UN Economic Commission for Africa (ECA) Subregional Office for Southern Africa (SRO-SA) has called on countries in the region to accelerate regional integration, strengthen economic resilience and implement coordinated policy responses to withstand external shocks. The Middle East crisis represents another major external shock, following the Covid-19 pandemic and Russia's invasion of Ukraine, which threatens to reverse the region's hard-won macroeconomic gains, said ECA SRO-SA director Eunice Kamwendo.
