After Bulgarian Prime Minister Boiko Borissov took his turn among a succession of heads of state and government to have talks with United Nations Secretary-General Ban Ki-moon at the start of the General Assembly’s new season, the UN’s news service said that Kosovo had topped the agenda, specifically the prospects for talks between Belgrade and Priština.Given hopes in diplomatic circles that on the sidelines of the General Assembly talkfest, an arrangement could be brokered to open negotiations between Serbia and Kosovo, the topic of the Borissov-Ban discussions was hardly a surprise – especially given Bulgaria’s desire to take the lead in helping to get the Western Balkans on an even keel.
