Serbian President Aleksandar Vucic said Serbia would react in serious, responsible and decisive manner if a referendum on unification of Kosovo and Albania would happen, Tanjug news agency reported. He made these remarks while asked to comment on the statement of Kosovo President Hashim Thaci who said earlier if the EU continues with the isolation of Kosovo, he would think of institutional measures and unification with Albania. Vucic added he has warned the EU about that. “When I asked people from the EU that Pristina does not adopt a platform which is against the dialogue, UN SC Resolution 1244 and declaration on genocide, from Brussels they told me it will not happen, they will not adopt that. Three days ago I told them what Thaci said to me and they repeated the same – it won’t happen,” Vucic said.
