Escalation of tensions on the border between Kosovo and Serbia raised concerns in Europe and in the US about a potential spillover to the rest of the Balkans.     In this episode of #BalkansDebrief, Ilva Tare speaks to Petrit Selimi, Former Foreign Minister of Kosovo and CEO of Millennium Foundation Kosovo, about the frictions that followed Kosovo's announcement of the reciprocity principle. Has the crisis been averted or postponed for a month? Will the involvement of EU Commission Vice President Borrell ensure continued dialogue between President Vucic and Prime Minister Kurti? Has Russian support for Serbia made the dialogue more difficult? How can regional cooperation in the Western Balkans be unlocked?
