Berlin: German Chancellor Angela Merkel has said the European Union cannot allow Greece, a country bailed out from its huge debt crisis, to plunge into "chaos" by shutting European borders to refugees.
"Do you seriously believe that all the euro states that last year fought all the way to keep Greece in the eurozone -- and we were the strictest -- can one year later allow Greece to, in a way, plunge into chaos?" Merkel said in a TV interview.
Merkel criticised the move by Austria and several Balkan countries to introduce border controls or cap daily migrant arrivals, creating a bottleneck in Greece as refugee boats continue to arrive from Turkey.
"What has happened is exactly what we feared, that a country is now left alone with its problems, and we can't allow that," the German leader said in a lengthy interview on the migrant crisis with public broadcaster ARD.
Merkel -- who had long sparred with Greek Prime Minister Alexis Tsipras, demanding strict austerity in return for billions in EU-IMF bailouts -- said she was now in close contact with the leftist leader on the refugee influx.
Anger has been building in Greece, the European gateway for hundreds of thousands of migrants, after Vienna introduced a daily cap on asylum applications and four Balkan countries, Macedonia, Serbia, Croatia and Slovenia, tightened entry conditions.
Germany last year took in over one million asylum seekers, more than half from war-torn Syria, Iraq and Afghanistan, leaving Merkel exposed to rising criticism at home as well as from many EU partners.
Merkel insisted that the refugee influx be reduced through tightening EU external borders, involving NATO ships in a surveillance mission to stop refugee boats from Turkey, and an EU deal with Ankara.
"But many don't believe in this way and are saying 'well, who knows whether that will work?' said the chancellor.
Merkel said of eastern European countries that have tightened their border controls: "The problem is that they acted independently and unilaterally, but it's not good if a country is not involved."
She added: "Greece was simply left on the outside. The border was secured from the Macedonian side, without anyone speaking with Greece about whether Greece wanted to secure its borders too."
Merkel said Germany's responsibility was "not to solve the problem at the expense of another country but together with other countries. That's what we did in the euro crisis and that's what we have to do in the refugee crisis.
