The paper’s purpose is to explore the policy implementation of African polity amidst economic integration development and sustainable growth. Most African countries have, over the years, suffered from severe macroeconomic disequilibria, foreign debt service burdens, over-valued currencies, and lack of policy Implementation; this caused linger highly behind in terms of development. In these situations, it is logical for one to expect the full integration of Africa in terms of trade and migration, using the Southern African subregional integration as a case study. Qualitatively, this paper collected and analyzed data based on content, using secondary sources from different domains. The neo-functionalist theory was applied, and findings show a failure to meet set targets in the SADC plan, which has established a bad precedent for the subregions for African development. The failure is seen as lacking ethical leadership. It recommends that there is a need for African states to improve their infrastructure, recognize the capacity of the private sector to generate wealth, and induce development with open economies to member states.
