Gabon and Equatorial Guinea Resolve Long‑Standing Island Dispute
On Tuesday, Gabon and Equatorial Guinea formally ended a territorial disagreement that has persisted since the early 1970s over three small islands in the Gulf of Guinea. The agreement, signed at the African Union headquarters in Addis Ababa, commits both nations to respect the 2023 ruling of the International Court of Justice (ICJ) that awarded sovereignty of the islands to Equatorial Guinea.
Background of the Dispute
The contested territory consists of:
- Mbanie – approximately 30 hectares, the largest of the three features.
- Cocotiers – a low‑lying sand cay.
- Conga – another modest sand formation.
Although the islands are virtually uninhabited, they sit in a maritime zone that geological surveys suggest could hold significant oil and natural gas reserves.
The roots of the disagreement trace back to colonial demarcations. In 1900, France and Spain signed the Treaty of Paris, establishing a boundary that placed the islands under Spanish administration. After Equatorial Guinea gained independence in 1968, the territory transferred to the new state. Gabon later argued that the 1974 Bata Convention—a bilateral agreement between Gabon and Spain—superseded the 1900 treaty and granted the islands to Gabon.
Unable to settle the matter diplomatically, both countries submitted the question to the ICJ in 2021, asking the court to determine which treaty held legal weight.
ICJ Ruling and Its Implications
In May 2023, the ICJ delivered its judgment, stating that the 1974 Bata Convention did not create a valid legal title to the islands. The court concluded that the islands remained under the sovereignty derived from the 1900 Treaty of Paris, which had been transferred to Equatorial Guinea upon independence.
The decision was based on:
- Analysis of the treaty texts and subsequent practice of the parties.
- The principle of uti possidetis juris, which preserves colonial borders at the moment of independence.
- Lack of evidence that Gabon exercised effective control over the islands after 1968.
The ruling is final and binding under the Statute of the ICJ, giving both states a clear legal framework for moving forward.
Signing Ceremony at the African Union
The formal agreement was signed by:
- Simeon Oyono Esono Angue, Minister of Foreign Affairs, Equatorial Guinea.
- Dieudonne Aba’a Owono, President of Gabon’s Constitutional Council.
- Mahmoud Ali Youssouf, Chairperson of the African Union Commission, who also acted as a witness.
During the ceremony, Minister Angue declared, “This matter has been resolved once and for all,” emphasizing that the two nations can now focus on shared priorities. Aba’a Owono added that the accord “opens a new era of cooperation with Equatorial Guinea.”
The African Union welcomed the settlement, noting that prolonged border disputes hinder regional integration and development. The AU’s involvement underscores its role as a facilitator of peaceful conflict resolution in Africa.
Looking Ahead: Cooperation and Resource Management
With the legal uncertainty removed, Gabon and Equatorial Guinea can proceed to:
- Jointly explore and manage potential hydrocarbon resources in the surrounding waters.
- Establish maritime security patrols to protect fisheries and prevent illicit activities.
- Collaborate on environmental monitoring to safeguard the fragile marine ecosystem.
- Develop infrastructure projects, such as joint research stations or shared logistics hubs, that benefit both economies.
Experts in maritime law and regional economics note that clear sovereignty reduces investment risk, making the area more attractive to responsible energy companies. Furthermore, the agreement sets a precedent for other African nations facing similar colonial‑era border ambiguities.
By adhering to the ICJ’s verdict and committing to peaceful cooperation, Gabon and Equatorial Guinea demonstrate how international legal mechanisms, backed by regional organizations like the AU, can transform long‑standing disputes into opportunities for mutual growth.
