Serbian President Aleksandar Vucic said on March 14 that Serbia is ready for a compromise over dispute with Kosovo, which is key to Serbia’s bid to join the European Union.

The EU insists that the normalization of ties between Belgrade and Pristina is a key condition they both must meet in order to join the bloc.

“For us, the most difficult obstacle on the road to Europe is indeed the situation over Kosovo, and because of that, Serbia is …. ready to talk about possible compromises,” Vucic told reporters.

He spoke after meeting with Wess Mitchell, the U.S. acting assistant secretary of state for European affairs.

Mitchell is on a tour of the region that has already taken him to Kosovo and Macedonia.

“We can accept only a compromise … but not a humiliation of our own people,” Vucic said.

Vucic and Mitchell expressed deep disagreement over the establishment of Kosovo’s armed forces.

Mitchell insisted that Kosovo had a “legitimate right” to form a professional army that would include ethnic Serbs, and said such a force does not present a threat for Serbia.

“Serbia is against it,” Vucic said, arguing there was no legally-binding document that would give Pristina the right for such a move.

Kosovar President Hashim Thaci has repeatedly said Kosovo would form an army.
