(ANSA) - PRISTINA - By continuing to regard Kosovo as a part of Serbia, president Aleksandar Vucic shows that he is ''far from reality'', Kosovo's president Hashim Thaci said today. Speaking to journalists in Pristina, Thaci confirmed that the last negotiation session with Vucic held on Wednesday in Brussels, and mediated by the EU's High Representative Federica Mogherini, was very brief and extremely tense and difficult. ''It was not easy to talk with Vucic who continues to believe that Kosovo is a part of Serbia's territory, the heart of Serbia, and that position is far from reality'', said Thaci, cited by local media. Kosovo's president reiterated his conviction that the dialogue between Pristina and Belgrade will lead to the mutual recognition of sovereignty, in the interests of both parties. (ANSA).
