The European Union is concerned Turkey is maintaining a close partnership with Russia despite the war in Ukraine and tough Western sanctions against Moscow. The deepening economic ties between Turkey and Russia is "a cause for great concern," EU foreign policy chief Josep Borrell said in a letter to the European Parliament, Germany media reported on December 11. Also of concern was Turkey's continued policy of "not joining the EU's restrictive measures against Russia," the letter said. It was important that Turkey not offer Russia any workarounds to sanctions, Borrell cautioned.
