The Embassies of the Eastern Caribbean States and Missions to the European Union is a unique joint diplomatic mission representing the Commonwealth of Dominica alongside St. Kitts and Nevis, Saint Lucia, and St. Vincent and the Grenadines. This collaborative approach reflects the strong bonds and shared interests among OECS member states. The mission works to strengthen political, economic, and cultural ties between the Eastern Caribbean region and the European Union, its member states, and institutions. By pooling diplomatic resources, OECS countries achieve greater influence and efficiency in advancing their collective interests on the international stage, particularly on issues affecting small island developing states such as climate resilience, sustainable development, and preferential trade arrangements. Brussels, the de facto capital of the European Union, hosts the headquarters of major EU institutions including the European Commission, European Council, and European Parliament. This makes it an essential location for OECS countries to maintain diplomatic representation. Located in the heart of Brussels at Rue de Livourne 42, the OECS mission benefits from proximity to European Quarter diplomatic and institutional buildings.
