Serbia's delegation at the meeting of the Southeast Europe Cooperation Process (SEECP) taking place in the Bulgarian sea resort of Pomorie, headed by the President Boris Tadic, left in protest after the Kosovo delegate Skender Hiseni was allowed to speak.
According to the Serbian representative, the political director of UNMIK Dzolio Nagele has violated the procedure by giving the right to speak to Hiseni, who presented himself as Kosovo's foreign minister.
The Serbian delegation reacted but after its objection was rejected, it proceeded to leaving the meeting.
Serbia's President Boris Tadic declared his country would never give up its territorial integrity as well as its EU perspective.
"Serbia will never recognize the unilaterally declared independence of Kosovo, and no one has the right to set this as a condition for its EU membership", Tadic said adding his state had the legitimate right to become a EU member.
