This World Bank report outlines the impetus for creating a single digital market (SDM) in East Africa, which would drive deeper integration and spur increased dynamism of the digital economies of six East African countries: Burundi, Kenya, Rwanda, South Sudan, Tanzania and Uganda. It argues that East African countries simply do not have the size and resources to meet all these needs on their own nor the luxury of time to address these challenges gradually without falling further behind. The East Africa SDM initiative is designed to help the region’s citizens, businesses, and governments rise to the challenge and seize opportunities at hand. It aims to bring together the region’s digital leaders and stakeholders to rally around a common vision for the region’s digital aspirations and a coordinated blueprint that can turn this vision into reality. By working together, East African countries and their development partners can maximize the impact of their investments and reforms to enhance their economic competitiveness and achieve digital transformation far greater than the sum of its parts.
