Aleksandar Rakovic

Academician Matija Beckovic has also been banned, as well as Serbian politician and lawyer Dejan Mirovic, as they endanger the national security of Montenegro.

After media reported on Thursday that Montenegrin police have barred four Serbian cultural, academic and legal figures from entering the country, Serbian President Aleksandar Vucic condemned the decision and vowed to respond. 

"The crossing of the state border, beside Beckovic, has also been denied to historians Cedomir Antic and Aleksandar Rakovic, as well as Serbian politician and lawyer Dejan Mirovic," the daily Dan was told by the Border Police.

The website also said that Yee told Greek media no decision had been made to appoint him as US ambassador in one of the Balkan countries - something Serbian media previously often speculated about.
