"Everything that would be managed to achieve at the summit is good, but it cannot be relied on. The EU must also protect its own external borders," Faymann said in remarks broadcast by the European Commission audiovisual services.
The EU-Turkey summit focusing on stemming migration flows into the bloc is taking place Monday in Brussels. The EU leaders are expected to ask Ankara to prevent refugees in Turkey from fleeing to Europe and resettle migrants, whose asylum requests in EU states were rejected.
Europe has been beset by a refugee crisis, with hundreds of thousands of undocumented migrants fleeing their home countries in the Middle East and North Africa to escape violence and poverty, with many of those using the so-called Western Balkan route to get into the western EU states.
Brussels and Ankara drafted the EU-Turkey action plan in November 2015, under which EU member states pledged to pay Turkey 3 billion euros over the next two years and fast-track Ankara’s EU accession talks in exchange for efforts to limit migrant arrivals.
