The European Broadcasting Union (EBU) excluded Russia from the Eurovision Song Contest (ESC) in May in Turin on Friday evening.
The decision came after a recommendation from the ESC reference group, which represents the member states and ensures compliance with the rules.
The decision reflects concerns that, given the unprecedented crisis in Ukraine, involving a Russian participant would bring discredit to the competition, the EBU said in a brief statement circulated via Twitter.
We will continue to protect the values that this cultural competition stands for, which aims to promote international exchange and understanding for one another and to bring audiences together to celebrate diversity through music and a united Europe on stage.
Shortly before, the EBU had announced that Russia could take part in the ESC, but was concerned about the aggression against Ukraine.
The Ukrainian broadcaster Suspilne had called for Russia to be excluded because the country, as an aggressor and violator of international law, was undermining the ideals of the competition.
Ukraine will compete with the band Kalush Orchestra and the song "Stefania".
The group had come in second place in the national preliminary round, but since the winner Alina Pash canceled her participation for political reasons, the runners-up moved up.
