This document aims at supporting and facilitating EU enlargement to the Western Balkans. It offers practical guidelines for national administrations, parliaments and civil society organisations (CSOs) in order to encourage their advocacy efforts to accelerate accession to the EU and contribute to the development of positive perceptions of the region in the Brussels institutions, EU Member States, as well as the Western Balkans. The future regional and national advocacy strategies stemming from these guidelines are expected to synergise with other regional mechanisms/leverages for the faster European integration.
