Greece said on Monday the European Union had offered to pay the costs of accommodating 20,000 more migrants in temporary camps on its islands as the bloc struggles to improve its managament of the flow of refugees across Europe.
More than half a million migrants have transited Greece so far this year, many of them fleeing Syria's civil war. Most move on to destinations in wealthier western and northern Europe, especially Germany.
Greece, mired in a multi-year economic crisis, made clear its readiness to provide shelter for more refugees was strictly conditional on the EU financial aid and on the understanding that those offered shelter would later be relocated.
"What we did manage to extract (from EU partners) was that this would be financed by the European Union, something that was not the case until now. Their (the new camps') creation will depend on financing," Migration Minister Ioannis Mouzalas told Skai radio.
Asked if it were possible to have the facilities set up by the end of this year, he said: "If the financing is available it is, if financing is not available it won't be."
His comments came a day after EU leaders agreed at a mini-summit in Brussels to cooperate in managing the flow of migrants through Greece and the Balkans to help ease a crisis that threatens to set European states against one another.
The EU's new 17-point action plan includes United Nations-aided accommodation for 100,000 people, half of them in Greece.
The vice-president of the European Commission tried to reassure Greece of the EU's willingness to provide more cash.
"From the Commission's point of view, we are willing to find additional means of supporting those countries which are most exposed to the refugee crisis and Greece is among them," Valdis Dombrovskis told a news conference in Athens on Monday.
The 20,000 new places will be in addition to some 30,000 Greece already agreed at an earlier EU summit to provide for refugees. But these figures are small compared to the sheer numbers of people now arriving.
MORE CASH NEEDED
Last week, in an upsurge of refugees before the onset of winter, an estimated 10,000 people were arriving on a daily basis on Greece's outlying islands, mostly from non-EU Turkey.
"We already need 100 million euros for the identification and relocation on the islands," a government source told Reuters, adding that Greece had spent 1.5 billion euros in recent years on reception centres and staff to deal with the refugees.
Greece says the most effective way to deal with the crisis is resettling refugees directly from camps located in Turkey to EU member states, thereby easing the transit crisis.
But Greece has also come under fire for failing to document all the people crossing its territory.
Prime Minister Alexis Tsipras said after Sunday's summit that EU border security agency Frontex would provide assistance in registering refugees at Greece's northern borders.
