The Dimensions of Ethiopia’s Role in the Sudanese Crisis and Strategies of Deterrence

Dr Al-Haytham Al-Kindi Yousif
Relations between Sudan and Ethiopia in the post-colonial era have been characterised by cautious cooperation and the exchange of leverage. Despite geographical proximity and strong people-to-people ties, the political relationship has long been governed by a strategy of supporting each other’s opposition movements, with Khartoum and Addis Ababa hosting and backing rebel groups as instruments of mutual pressure for decades.
Since the outbreak of the 15 April war, however, this relationship has entered a more complex phase. Addis Ababa appears to be playing a behind-the-scenes role, seeking to turn Sudan’s catastrophe into an opportunity to address its domestic challenges and external strategic concerns.
To understand this dynamic, we must first answer a key question:
What does Ethiopia stand to gain from supporting the Rapid Support Forces (RSF)?
Ethiopia’s approach to the Sudanese crisis cannot be separated from a calculation of costs and benefits. This approach is reflected in four strategic dimensions:
1. Economic Recovery and Military Support
The Ethiopian economy is facing severe challenges. In this context, Emirati financial assistance and investment—given the UAE’s alliance with the RSF and its position as a major investor in the Grand Ethiopian Renaissance Dam (GERD)—represent an important economic lifeline for Addis Ababa.
This partnership also helps secure access to advanced military equipment, particularly Turkish and Chinese drones, which previously played a decisive role in Ethiopia’s campaigns against the Tigray insurgency and Fano forces in the Amhara region. These capabilities were instrumental in preventing what many viewed as an imminent threat to the government in Addis Ababa.
2. The Water Question and the Future of Al-Fashaga
Weakening Sudan’s firm negotiating position regarding the GERD constitutes a strategic objective for Ethiopia.
The emergence of an alternative authority in Khartoum that is more accommodating to Ethiopian interests could facilitate the resolution of this issue in Addis Ababa’s favour. It could also revive proposals for a tripartite Sudanese-Ethiopian-Emirati partnership to develop the fertile Al-Fashaga lands, which, in practice, would legitimise Ethiopian influence there and diminish Sudan’s effective sovereignty over the territory.
3. Exporting Domestic Crises and the Quest for a Seaport
Engagement in Sudan’s affairs provides Ethiopia with an external issue around which domestic public opinion can be rallied, diverting attention from internal ethnic conflicts involving the Tigray, Amhara, and Oromo populations.
At the same time, Ethiopia’s ambition to secure access to the Red Sea is constrained by the strong relationship between Eritrea and the Sudanese government. Weakening the legitimacy of the Sudanese state would therefore indirectly undermine Eritrea’s strategic position, potentially making it easier for Addis Ababa to pursue its long-standing objective of obtaining maritime access.
4. Logistical Support and Proxy Warfare
International reports, supported by images and documentary evidence, have alleged that Ethiopia has provided logistical assistance to forces linked to the conflict. These allegations include the existence of border-area training camps that contributed to military developments in parts of the Blue Nile region, including areas around Kurmuk.
Reports have also pointed to the use of Ethiopian airspace by aircraft travelling from Abu Dhabi towards Nyala Airport, the treatment of wounded RSF personnel, and the transformation of Addis Ababa into a political platform for leaders of the Taqaddum coalition and other Sudanese political groups opposed to the Sudanese Armed Forces.
How Should Sudan Respond?
If these are indeed the motivations driving Ethiopian involvement in the Sudanese crisis, then the next question concerns Sudan’s response.
Sudan must adopt a clear deterrence strategy to counter any efforts to weaken or destabilise the state. This requires moving beyond traditional diplomacy and implementing a comprehensive set of measures.
First: Strengthening Internal Cohesion
Any effective external deterrence begins with a unified domestic front. Political and social divisions provide opportunities for regional actors to advance their agendas.
Sudan, therefore, needs to build a broad national consensus that transcends narrow partisan interests and supports the country’s legitimate institutions, foremost among them the Sudanese Armed Forces. Such cohesion would reduce opportunities for external actors to exploit domestic political constituencies to legitimise armed groups.
Particular attention should also be paid to preventing tribal and regional polarisation, especially in areas bordering Ethiopia, where attempts to exploit local divisions remain a persistent concern. Traditional leaders, community organisations, and local authorities should work together to strengthen social resilience and national awareness.
The management of refugee issues is equally important. Sudan hosts substantial numbers of Ethiopian refugees, and while humanitarian obligations must be respected, effective monitoring mechanisms are necessary to prevent any potential exploitation of refugee communities for intelligence or political purposes.
Second: Securing the Blue Nile Front
The Blue Nile region represents a critical strategic theatre in Sudan’s relationship with Ethiopia.
Any attempt to establish instability along this frontier could create a corridor linking Ethiopian territory with areas controlled by armed groups. Sudan must therefore strengthen its control over border areas, particularly along the Kurmuk–Qaisan axis, close security gaps, and prevent the movement of personnel and supplies from across the border.
The defeat of insurgent activity in the Kurmuk area would also help protect vital national infrastructure, including the Roseires Dam, which is of central importance to Sudan’s water security and electricity generation.
In addition, organised popular resistance forces drawn from local communities could be incorporated into defensive structures under the supervision of the Sudanese Armed Forces, thereby strengthening local resilience and denying adversaries the numerical advantage.
Third: Robust Diplomacy and Legal Documentation
Sudan should intensify its diplomatic efforts by presenting documented evidence to the United Nations Security Council and the African Union concerning any alleged external support provided to armed groups operating inside Sudan.
The objective should be to move the issue from the realm of speculation into a transparent international discussion based on verifiable facts.
Fourth: Activating Regional Pressure Points
This would involve closer security and military coordination with Egypt on border security and Nile water issues, as well as enhanced cooperation with Eritrea regarding Red Sea security concerns.
At the same time, Sudan could seek to exploit Ethiopia’s internal vulnerabilities by strengthening contacts with groups opposed to Prime Minister Abiy Ahmed, thereby increasing the strategic costs of any continued support for destabilising activities within Sudan.
Fifth: A Conditional Economic Initiative
Sudan should link economic cooperation and border stability—particularly in Al-Fashaga and Benishangul-Gumuz—to Ethiopia’s recognition of the legitimacy of the Sudanese state and its institutions.
Addis Ababa must be made to understand that reliance on armed non-state actors is ultimately a losing strategy that risks creating a belt of instability capable of engulfing the entire region.
Conclusion and Future Outlook
Ultimately, Ethiopia’s approach to the Sudanese crisis represents a tactical gamble fraught with risks.
The pursuit of short-term economic and geopolitical gains through support for an armed militia overlooks a fundamental reality: the fragmentation of the Sudanese state would not stop at Sudan’s borders. Instead, it could trigger a domino effect that extends into Ethiopia itself, a country already burdened by complex ethnic and political tensions.
Sudan’s leadership must recognise that confronting regional interference requires moving beyond appeals and diplomatic protests towards a comprehensive deterrence strategy. Such a strategy must be built upon a cohesive internal front, a strong military presence in the Blue Nile region, and the intelligent use of geopolitical leverage.
Only through this combination can Sudan compel Addis Ababa to reassess its calculations and recognise that stability in the Horn of Africa depends upon a strong and united Sudan—not upon parallel armed entities, cross-border militias, or regional projects that ignore the dangers of the fire already burning in the region.
