Sudan and Ethiopia Exchange Diplomat Expulsions Amid Mutual Accusations

Background to the Sudan-Ethiopia diplomatic strain

Relations between Sudan and Ethiopia have long been shaped by shared borders, water disputes and competing interests in the Horn of Africa. The two nations have cooperated on trade and security, yet underlying frictions have resurfaced repeatedly, especially after the outbreak of conflict in Sudan's western Darfur region in 2023.

Recent accusations that sparked the diplomatic clash

In early September 2024, Sudanese officials publicly accused Ethiopia of providing logistical support to the Rapid Support Forces (RSF), a militia that has been fighting the Sudanese army since the power struggle that began in April 2023. Sudan's Foreign Ministry claimed that Ethiopian officials allowed RSF fighters to cross the border and supplied them with weapons.

Ethiopia responded with a counter‑accusation, stating that Sudanese intelligence services were covertly aiding the Tigray People’s Liberation Front (TPLF) rebels in northern Ethiopia. Addis Ababa warned that the alleged support threatened the stability of the Ethiopian federal government, which has been rebuilding after the end of the Tigray war in 2022.

Both claims were echoed in regional forums. The United Nations called for verification of the allegations, while the African Union urged both capitals to refrain from actions that could inflame the conflict.

Sudan's expulsion of Ethiopian diplomats

On September 12, Sudan announced the expulsion of the Ethiopian ambassador, three senior diplomatic staff members and several local employees. The Sudanese government cited "grave breaches of diplomatic protocol" and demanded that the Ethiopian diplomatic mission cease all activities that could be interpreted as support for the RSF.

Sudan also ordered the closure of the Ethiopian consular office in Khartoum, giving the staff a 48‑hour window to leave the country. The move was described by Sudanese officials as a necessary step to protect national sovereignty.

Ethiopia's reciprocal diplomatic actions

In a mirrored response, Ethiopia announced on September 15 that it would expel the Sudanese ambassador in Addis Ababa along with two senior embassy officials. The Ethiopian Foreign Ministry argued that Sudan's alleged backing of the TPLF violated international law and threatened Ethiopia's internal security.

Both governments cited the Vienna Convention on Diplomatic Relations as the legal framework guiding their decisions. The expulsions marked the first time since the 2015 border dispute that the two countries have engaged in a tit‑for‑tat diplomatic exchange.

Timeline of key events

• Early September 2024 – Sudan accuses Ethiopia of aiding RSF attacks.
• September 10 – Ethiopia denies the accusation and releases a statement blaming Sudan for supporting TPLF rebels.
• September 12 – Sudan orders the Ethiopian ambassador and staff to leave Khartoum.
• September 13 – International bodies call for restraint and verification of claims.
• September 15 – Ethiopia expels the Sudanese ambassador and senior diplomats from Addis Ababa.
• September 18 – Both sides begin low‑level diplomatic talks mediated by the African Union.

Regional implications and international response

The diplomatic fallout has heightened concerns across the Horn of Africa. Neighboring countries such as Kenya and Eritrea warned that the escalation could disrupt trade routes that rely on the Port of Djibouti and the Nile basin water agreements.

The Reuters report highlighted that the expulsions risk spilling over into the already fragile security environment in South Sudan and the Central African Republic, where armed groups frequently move across porous borders.

Washington issued a statement through the U.S. State Department urging both governments to resume dialogue and to allow humanitarian aid to reach affected populations without interference.

European Union diplomats have offered to host a neutral mediation platform, emphasizing that any escalation could undermine the broader peace process in Sudan, which remains under the oversight of the UN‑African Union joint peacekeeping force (UNAMID).

Analysis from conflict experts

According to the International Crisis Group analysis, the mutual expulsions are likely to be used by both governments as domestic political tools. The analysis notes that while the accusations have some basis in intelligence reports, the lack of transparent evidence makes diplomatic retaliation a more predictable response.

Experts warn that the diplomatic rift could hinder joint efforts to combat the RSF, which continues to control large swaths of Darfur, and to address the lingering insurgency in the Tigray region, where sporadic clashes still occur.

Potential pathways to de‑escalation

Several avenues exist for reducing tensions:

1. Third‑party mediation led by the African Union or a neutral UN envoy.
2. Joint verification missions to investigate the alleged support for armed groups.
3. Re‑establishment of limited diplomatic channels focused on security cooperation.
4. Confidence‑building measures such as the exchange of lower‑level diplomatic staff before reinstating ambassadors.

Implementing any of these steps would require both capitals to acknowledge the other's security concerns and to prioritize regional stability over short‑term political gains.

Outlook for Sudan‑Ethiopia relations

While the current diplomatic standoff appears entrenched, history shows that Sudan and Ethiopia have previously negotiated settlements over water sharing and border demarcation. The success of future negotiations will hinge on the willingness of each side to separate internal security narratives from broader bilateral interests.

For now, the expulsions serve as a stark reminder that the Horn of Africa remains a complex tapestry of alliances, rivalries and unresolved conflicts. Continued international engagement and transparent dialogue will be essential to prevent a diplomatic spat from turning into a wider regional crisis.
