Austria says it will not budge on its tough border policy because a comprehensive deal with Turkey to stem migration to Greece is far from secured.
EU countries have not offered any firm concessions to Ankara in return for better cooperation on migration, and disagreements with Turkey on issues such as media freedom or the Kurdish minorities would likely continue, Chancellor Werner Faymann says.
"It would be an advantage to organize border controls with Turkey, but we cannot depend on it," he adds.
"We will not budge even a millimetre from our position. Macedonia will therefore remain closed," Interior Minister Johanna Mikl-Leitner says, referring to Austria's asylum quotas that have caused Macedonia to all but close its border with Greece.
