The document discusses regional integration in Eastern Africa through the Trade Facilitation Treaty Area (TFTA) and challenges to advancing integration. It notes that the TFTA aims to build on existing regional economic communities like the East African Community (EAC) and South African Development Community (SADC) to liberalize trade and investment. However, differences between member states like development levels and existing agreements could pose challenges to full integration. Deeper integration will require addressing non-tariff barriers, investing in infrastructure to support trade, and ensuring benefits to businesses and human rights. Overall, progressing from the TFTA to a Continental Free Trade Area will depend on how well integration is advanced at the regional economic community level first.
