The European Union will never recognize the Russian-occupied Crimean peninsula as legally Russian, the bloc’s top diplomat Kaja Kallas told Agence France-Presse (AFP) on April 22.

Kallas’ comments come in response to reports that the recognition of Crimea as Russian territory is being considered as part of a U.S.-backed proposal to end the war in Ukraine.

“Crimea is Ukraine,” Kallas told the AFP.
