Prime Ministers of Bulgaria, Greece and Romania, PMs Boyko Borissov, Alexis Tsipras and Mihai Tudose, respectively, will pay an official visit to Belgrade on December 8. Previously, PMs met with Serbian President in October in Varna, Bulgaria, where Vučić explained that meeting was not about establishing a new “Visegrad Group”, but “a way for us to be more united and stronger.”
