Guyana is seeking a definitive legal resolution to the long-standing territorial dispute with Venezuela over the Essequibo region, moving away from the diplomatic framework established by the 1966 Geneva Agreement. The government in Georgetown is prioritizing a final judgment from the International Court of Justice (ICJ) to establish a permanent border, arguing that decades of negotiations under the Geneva Agreement have failed to produce a result.
The dispute centers on the Essequibo, a vast territory comprising approximately two-thirds of Guyana’s landmass. Venezuela claims the region, asserting that the border was illegally shifted in the late 19th century. Guyana maintains that the boundary was settled by the 1899 Arbitral Award, which granted the territory to then-British Guiana.
The Limitations of the Geneva Agreement
The 1966 Geneva Agreement was signed between the United Kingdom, as the colonial power, and Venezuela shortly before Guyana gained independence. The pact established a framework for the two parties to resolve their differences through negotiated settlements. However, Guyana now contends that this mechanism has become a tool for procrastination rather than resolution.
For Guyana, the Geneva Agreement is viewed as a procedural roadmap that has been exhausted. The administration argues that Venezuela has used the agreement to avoid a binding legal ruling while continuing to challenge the validity of the 1899 border. By shifting the focus to the ICJ, Guyana seeks to move the dispute from a political negotiation, where power imbalances can dictate terms, to a legal forum based on international law.
The shift in strategy is driven by the need for legal certainty. Guyana requires a recognized, immutable border to secure its sovereignty and facilitate long-term infrastructure and economic planning within the Essequibo region.
The Impact of Oil Discoveries
The urgency to resolve the dispute has intensified following the discovery of massive offshore oil reserves in the Stabroek Block, located off the coast of the Essequibo. These discoveries, led by ExxonMobil and its partners, have transformed Guyana into one of the fastest-growing economies in the world.
Venezuela has responded to these developments by increasing its claims to the maritime territory and the adjacent land. In December 2023, Venezuela conducted a national referendum in which the government claimed citizens voted to create a new Venezuelan state called Guayana Esequiba and to grant Venezuelan citizenship to the inhabitants of the region.
Guyana asserts that the oil reserves are located within its sovereign waters as defined by the 1899 award. The government argues that the Geneva Agreement is insufficient to protect these assets from unilateral claims and that only a binding ruling from the ICJ can provide the necessary international protection for its economic activities.
Venezuela’s Position and the ICJ
Venezuela rejects the jurisdiction of the ICJ, maintaining that the 1966 Geneva Agreement is the only valid instrument for resolving the conflict. The Venezuelan government argues that the 1899 Arbitral Award was a “fraud” and is therefore null and void.
Venezuela has historically avoided the ICJ, preferring bilateral negotiations where it can leverage its larger military and economic size. However, the ICJ ruled in 2020 that it has jurisdiction to hear the case, a decision that Guyana has embraced and Venezuela has contested.
The current legal proceedings at the ICJ are focused on whether the 1899 award is legally binding. Guyana has presented evidence to support the validity of the award, while Venezuela has attempted to block the court’s proceedings through various diplomatic and legal challenges.
International Implications
The dispute has drawn significant international attention due to the risk of military escalation and the importance of the region’s energy resources. The United States, Brazil, and several Caribbean nations have called for a peaceful resolution and have urged both parties to avoid provocative actions.
Brazil, in particular, has acted as a mediator, hosting meetings between the two nations to prevent conflict on its own borders. Despite these efforts, the fundamental disagreement remains: Guyana seeks a legal end to the dispute via the ICJ, while Venezuela insists on a negotiated settlement under the terms of the 1966 agreement.
As of May 2026, the ICJ continues to process the case, and Guyana remains committed to the legal path, viewing the transition away from the Geneva Agreement as the only viable way to ensure the territorial integrity of the nation.
