The Southern African Development Community (SADC) is a large and dynamic regional economic community (REC) with the second highest level of regional integration among all African RECs. It has also been at the forefront of regional investment policymaking in Africa, with the Finance and Investment Protocol, the Investment Policy Framework, and the SADC Model Bilateral Investment Treaty. However, like much of Africa, SADC faces difficulties in attracting foreign direct investment which can contribute to sustainable development in the region. This report introduces newly developed OECD tools and analysis to the SADC region, including both FDI Qualities and a database on investment incentives. It is designed as a baseline diagnostic to explore ways to reinvigorate the reform of the SADC investment climate in order to prepare the region for the African Continental Free Trade Area, while also focusing on how to improve sustainable outcomes from investment. The report explores the national regulatory framework encapsulated in national investment laws and how this compares with initiatives at a regional level, investment promotion and facilitation in SADC, investment incentives, investment for green growth and responsible business conduct.
