Accession of Kosovo to the European Union
In May 2018, Bulgaria - holding the rotating presidency of the Council of the European Union - hosted a summit on the Western Balkans, which aimed to facilitate accession by the six, including enhanced regional security cooperation and regional connectivity. It was noteworthy that the Summit referred to 'partners' rather than states: this reflects the issue that Kosovo is only partially recognised as a state. The European Commission is sensitive to the issue which was addressed in a speech by the EU's High Representative/Vice-President Federica Mogherini at the European Parliament Plenary Session on the Western Balkan Strategy: " shared, unequivocal, concrete perspective for European Union integration for each and every one of the six partners. Each at its own pace, with its own specificities and under different conditions, but the direction is clear and is one ".
