Vanuatu pushes France to accept ICJ jurisdiction in Pacific islands dispute

Vanuatu has submitted an application to the International Court of Justice requesting that the court address its claims to sovereignty over two small Pacific islands: Umaenupne (also known as Matthew Island) and Umaeneg/Leka (or Hunter Island). These islands are currently under French control and have been the subject of territorial disagreement since Vanuatu gained independence in 1980.

The core of Vanuatu’s argument centers on decolonization principles. The nation contends that its independence process remains incomplete without the return of these islands and asserts that the colonial-era administrative arrangement placing them under French jurisdiction occurred without consulting the Indigenous population of the region. The dispute is rooted in the broader history of European colonial rule in the Pacific.

The islands themselves are uninhabited volcanic formations located approximately 300 kilometres east of the French territory of New Caledonia and southeast of Vanuatu. Although small in size, control over them carries significant strategic and economic implications, as sovereignty extends to surrounding waters that contain valuable fishing rights and access to seabed resources.

Diplomatic efforts have preceded this legal action. France and Vanuatu held bilateral negotiations over the islands and their maritime boundaries in 2018 and 2019, with additional negotiations occurring in 2025. However, earlier this year Vanuatu indicated that these negotiations had stalled, prompting the decision to pursue the matter through the ICJ. The court will not immediately proceed with the case unless France voluntarily accepts its jurisdiction over the dispute. An ICJ statement confirmed that no action will be taken unless Paris consents to the court’s authority in this matter.

The territorial question has also become entangled in French domestic politics, with far-right political parties attempting to use the dispute as a political issue. These parties have accused the Macron government of willingness to cede French territory, allegations that Paris has consistently refuted.
