The leaders of Serbia and Kosovo on Friday held their first talks in 18 months on resolving one of Europe’s most intractable territorial disputes, agreeing to a face-to-face meeting next week on the “very difficult” process. Kosovo’s Prime Minister Avdullah Hoti and Serbian President Aleksandar Vucic held a video summit that was also joined by French President Emmanuel Macron and German Chancellor Angela Merkel. Serbia has refused to recognise Kosovo’s unilateral declaration of independence after the province broke away in the bloody 1998-99 war that was ended only by a NATO bombing campaign against Serb troops.
