Four East African and Horn of Africa nations have taken a major step toward deeper regional integration with the creation of the Djibouti–Ethiopia–South Sudan–Uganda (DESSU) Corridor Authority, a new body designed to coordinate a major trade and transport corridor linking the Red Sea to East Africa’s inland markets.
Representatives from Djibouti, Ethiopia, South Sudan, and Uganda signed the intergovernmental agreement in Djibouti, establishing the authority to manage and oversee the development of a multimodal corridor stretching from the Port of Djibouti on the Red Sea to inland cities including Addis Ababa, Juba, Gulu, and Kampala.
The initiative aims to improve regional connectivity, streamline trade logistics, and provide more efficient maritime access for landlocked countries in East Africa.
Strengthening a Key Regional Trade Route
The DESSU Corridor builds upon existing infrastructure, particularly the established road and rail links connecting Djibouti and Addis Ababa. The corridor will extend southward through Ethiopia into South Sudan via routes such as Paloich–Pagak and onward to Nimule, before continuing into northern Uganda.
For landlocked economies like South Sudan and Uganda, the corridor offers a potentially faster and more reliable route to international markets compared to current alternatives.
Officials involved in the agreement say the project could significantly reduce transit times and transportation costs while improving the flow of goods across the region.
Major Infrastructure Investments
The corridor’s development will involve large-scale infrastructure upgrades along several segments of the route. International partners are supporting improvements to roads, railways, border facilities, and digital logistics systems.
The European Union has already committed €32 million to upgrade the Djibouti–Ethiopia section of the corridor. The funding is delegated to Agence Française de Développement and implemented by TradeMark Africa as part of broader efforts to strengthen regional integration in the Horn of Africa.
The upgrades are expected to modernize customs procedures and logistics platforms, with the goal of cutting cargo transit times from the Port of Djibouti by as much as 50 percent.
Additional financial support is coming from the African Development Bank, which approved $214 million in late 2025 for the second phase of related transport corridor projects. These investments focus on road improvements and climate-resilient infrastructure across key sections of the route.
Coordinating Cross-Border Trade
The newly formed DESSU Corridor Authority will be responsible for coordinating development, managing operations, and monitoring performance across the corridor.
Its responsibilities will include harmonizing customs procedures, aligning cross-border regulations, attracting private investment, and ensuring efficient cargo movement between participating countries.
The authority is expected to begin operations in early 2026 with the establishment of a permanent secretariat and the rollout of operational frameworks for corridor management.
Supporting Africa’s Continental Trade Goals
The project aligns closely with broader continental initiatives such as African Union’s Agenda 2063 and the African Continental Free Trade Area (AfCFTA), which aim to improve infrastructure connectivity and expand trade across the continent.
By creating a unified governance structure for the corridor, the four participating countries hope to reduce logistical bottlenecks, lower trade costs, and strengthen economic cooperation.
For Ethiopia, the corridor reinforces its role as a regional transit hub. For South Sudan and Uganda, it offers a crucial alternative route to global shipping lanes and could significantly reduce the cost of importing and exporting goods.
A New Chapter for Regional Integration
In a region often challenged by infrastructure gaps, border delays, and complex logistics systems, the creation of the DESSU Corridor Authority represents a major collaborative step forward.
If successfully implemented, the corridor could reshape trade patterns across the Horn and East Africa, opening new opportunities for businesses, improving market access, and driving economic growth across the four nations.
