Equatorial Guinea and Gabon signed a Joint Engagement Agreement on Tuesday, July 29, 2026, ending a 50-year border dispute [1].

The resolution settles a long-standing conflict over three small islands in the Gulf of Guinea [1]. This agreement is critical for regional stability and the legal management of resource-rich maritime territories.

The signing ceremony was hosted by the African Union Commission [2]. The agreement serves to implement a judgment delivered by the International Court of Justice on May 19, 2025 [2]. That ruling provided the legal clarification necessary to determine the ownership of the three islands [3].

For five decades, the two governments remained in a state of disagreement over these territories [1]. The resolution follows the legal framework established by the court's 2025 decision, which favored Equatorial Guinea in the dispute over the oil-rich islands [3].

By formalizing this agreement, both nations commit to the boundaries defined by the court. The African Union said the signature of the engagement agreement was a step toward peaceful cooperation between the Republic of Equatorial Guinea and the Gabonese Republic [2].

Equatorial Guinea and Gabon signed a Joint Engagement Agreement ending a 50-year border dispute.

The resolution of this dispute removes a significant geopolitical friction point in the Gulf of Guinea. Because the contested islands are located in oil-rich waters, the legal certainty provided by the International Court of Justice and this subsequent agreement allows both nations to pursue energy exploration and maritime security without the risk of diplomatic or military escalation.
