Deepening regional integration within the Southern African Development Community (SADC) will raise potential growth for all member countries. Integrated economies will increase market size, trade opportunities and improve resource allocation across member countries. Key pillars of functioning regional integration are the free circulation of goods and services, mobility of workers and interconnected infrastructure. To boost regional integration, remaining tariff barriers and non-tariffs barriers should be removed. Ensuring greater compliance to agreements by SADC members will also facilitate intra-regional trade and cross-investments. More co-operation between competition authorities should facilitate harmonisation of competition rules in particular in services and transport-related services which would ease circulation of good and services. The other key pillars of regional integration (industrial policy, infrastructure, investment, financial integration and tax) are also reviewed.
