Ukraine's foreign ministry criticised Croatian President Zoran Milanovic on Tuesday for saying Crimea would never return to Ukrainian control, describing his comment as "unacceptable."
Russia seized the Black Sea peninsula from Ukraine in 2014. In remarks on Monday detailing his objection to Zagreb providing military aid to Kyiv, Milanovic said it was "clear that Crimea will never again be part of Ukraine".
"We consider as unacceptable the statements of the president of Croatia, who effectively cast doubt on the territorial integrity of Ukraine," Ukrainian foreign ministry spokesperson Oleg Nikolenko wrote on Facebook.
