Prime Minister Aleksandar Vucic visited Brussels on 21 April 2015, where he attended the meeting of the Western Balkans Six. He also had bilateral talks with President of the European Council Donald Tusk, European Commissioner for Neighbourhood Policy and Enlargement Negotiations Johannes Hahn and Albanian Prime Minister Edi Rama.

The Prime Minister underlined that Serbia is on the European path and that it continues to implement economic measures to improve the economic situation in the country, as well as dialogue with Pristina in order to contribute to political stability in the region. Vucic expects that the negotiating chapters will be opened in June and that Serbia will complete in the coming days the Action plan for chapters 23 and 24.
In the evening hours on 21 April 2015, Prime Minister Vucic participated in the next round on normalisation of relations between Belgrade and Pristina, which was mediated by EU HR for Foreign Policy Federica Mogherini. Prime Minister Vucic stated that the talks were difficult but that certain progress has been made in the fields of telecommunications, civil protection and energy. The working groups will now start preparing the next round of dialogue which will be held in May, Vucic said.
