"What has happened: the Greek government called back the Greek ambassador in Austria for consultations back to Athens. This is a diplomatic move that shows that Athens is discontented with the initiative taken by the Austrian government in convening a conference on the migration issues without inviting Greece," Voridis explained.
"In our view, this is not going to work because Greece is pivotal to how these things with migration are going to be handled. This conference will arrive at no practical results," Voridis warned.
Greece is used as a gateway by hundreds of thousands of refugees and migrants seeking to enter Europe. After coming ashore on Greek islands, many of them head north in search of passageways to more affluent Germany and Sweden.
