The meeting on Connectivity of the Western Balkans Six was organized in Brussels, 21 April 2015, under the auspices of European Commissioner for Neighbourhood Policy and Enlargement Negotiations Johannes Hahn and Commissioner for Transport Violeta Bulc. Delegation of the Republic of Serbia was headed by the Prime Minister Aleksandar Vučić.

The Brussels meeting confirmed the agreement of the core network through a joint statement and discussed concrete ways which would help implement the core transport network in the Western Balkans until 2030. The EU has announced that in the next few years around one billion euro in financial assistance would be provided for the improvement of connectivity within the region and its integration into the main traffic corridors in the EU. The focus will remain on ensuring that the Summit in August 2015 in Vienna will achieve concrete results based on specific investments projects.
