ADDIS ABABA, Ethiopia – In a ceremony hailed as a triumph of African diplomacy, Equatorial Guinea and Gabon on Friday signed a Joint Engagement Agreement committing both nations to the full implementation of the International Court of Justice’s May 19, 2025 judgment on their decades-old territorial and maritime dispute.
The signing, hosted by the African Union Commission, took place on the sidelines of the 49th Ordinary Session of the AU Executive Council, the gathering of foreign ministers from across the continent. The deal puts a formal legal and political framework around the ICJ ruling, which definitively delimited the land and sea boundary between the two Central African neighbors, including sovereignty over a string of disputed islands in the Corisco Bay.
The pact is the culmination of months of intensive, AU-facilitated dialogue directly between Equatorial Guinea’s President Teodoro Obiang Nguema Mbasogo and Gabon’s transitional President Brice Clotaire Oligui Nguema. That engagement was steered by AU Special Envoy Albert Shingiro, who shuttled between Malabo and Libreville to narrow differences over the practical steps required to translate the court’s legal pronouncement into reality on the ground and at sea.
“The Agreement signed today is much more than a legal instrument,” declared Edouard Bizimana, Burundi’s Minister of Foreign Affairs and current Chair of the AU Executive Council. “It is a testament to the political maturity of two African nations that have chosen dialogue over confrontation, cooperation over division, and respect for the rule of law over the use of force.”
Details of the Joint Engagement Agreement remain closely held, but AU officials familiar with the text say it establishes a bilateral implementation commission with a clear timetable for the withdrawal of any military or security presence from areas awarded to the other party, the joint demarcation of the newly defined maritime boundary, and the creation of a mechanism to manage cross-border resources such as fisheries and potential hydrocarbon reserves. The agreement also reportedly binds both states to accept any future clarifications from the ICJ should interpretive disputes arise.
The case, formally instituted in 2016, centered on the sovereignty of Mbañe, Cocotiers, and Congas islets, as well as the delimitation of the territorial sea, exclusive economic zone, and continental shelf. Tensions had flared periodically, including a brief occupation of one of the islets that raised fears of armed clashes before both sides agreed to pursue a judicial settlement. The ICJ’s judgment, delivered on May 19, 2025, was widely viewed as a balanced resolution that largely delimited a median line while assigning the contested islands based on historical and effective occupation evidence.
Diplomatic sources in Addis Ababa say the breakthrough came during a discreet face-to-face meeting between Presidents Obiang and Oligui in late 2025, held under the auspices of the AU and with Shingiro’s direct mediation. That encounter allowed the two heads of state to move beyond technical legal arguments and agree on a set of confidence-building measures that paved the way for Friday’s formal signing.
For the African Union, the accord reinforces a broader push to resolve border disputes through continental legal and political mechanisms rather than leaving them to fester. It follows successful AU mediation in other frontier cases and strengthens the Pan-African institution’s credibility at a time when unilateralism and geopolitical competition threaten the continent’s security architecture.
“This is Africa at its best – solving African problems with African mechanisms, grounded in the international law we have freely accepted,” Bizimana added, describing the deal as a model for other outstanding boundary disagreements.
Observers note that the implementation phase will be the true test. The joint commission is expected to hold its inaugural meeting within 60 days, with a preliminary progress report due at the next AU summit. Both Malabo and Libreville are expected to dispatch technical teams to begin the delicate work of mapping and, where necessary, relocating communities whose livelihoods straddle the newly drawn line.
The United Nations and regional body ECCAS (Economic Community of Central African States) quickly welcomed the agreement, offering logistical and technical support for the demarcation process. The UN Secretary-General’s office issued a statement commending the “statesmanlike conduct” of both Presidents and the AU’s “instrumental role” in turning the ICJ ruling into a durable peace-building tool.
With the ink now dry on the Joint Engagement Agreement, Equatorial Guinea and Gabon have charted a course away from the brinkmanship that once defined their maritime frontier. The challenge ahead lies in sustaining the same political will that transformed a contentious legal judgment into a shared blueprint for coexistence.
