Serbia has sent a protest note after the Croatian foreign minister called President Aleksandar Vučić a Russian “satellite” in the Balkans

Serbia on Sunday sent a protest note after Croatia’s foreign minister described President Aleksandar Vučić as a Russian “satellite” in the Balkans.

It was the latest spat between the two neighbors, which have been at odds for most of the time since the bloody breakup of Yugoslavia in the 1990s.

Croatian Foreign Minister Gordan Grlić Radman told N1 television on Saturday that Vučić must decide which side he is on, Russia or the European Union, “because it is impossible and uncomfortable sitting on two chairs at the same time.”

“He shouldn’t have a big dilemma,” Grlić Radman said, saying that Vučić can remain Moscow’s ally but “malign” Russian influence that could undermine the stability of the Western Balkans will not be allowed.

The populist leader and other Serbian officials reacted with anger.
