In December 2015, the EU opened first chapters during the accession conference with the Serbian delegation led by Vučić. He is one of the crucial figures in cooperation and EU-mediated dialogue between the governments of Kosovo and Serbia, advocating the implementation of the Brussels Agreement on the normalization of their relations. Following United States-mediated negotiations, Vučić signed an agreement in September 2020 to normalize economic relations with Kosovo, but also to move the Serbian embassy in Israel to Jerusalem. He is one of the initiators of Mini Schengen Zone, an economic zone of the Western Balkans countries intended to guarantee "four freedoms". Observers have described Vučić's rule as an authoritarian, autocratic or illiberal democratic regime, citing curtailed press freedom.
