The European Union could unravel if member states fail to agree a common approach to the refugee crisis and security challenges in the next few months, leaders meeting in the Swiss resort of Davos have warned.
A day after Austria announced a formal cap on the number of refugees it would allow in this year, raising pressure on German Chancellor Angela Merkel to do the same, top European politicians pleaded for a deal in which states would agree to accept quotas of refugees.
But they admitted that such an agreement remained elusive, with many countries, including much of central Europe, refusing to accept any migrants.
"I'm not naive," Swedish Prime Minister Stefan Lofven told reporters when asked about the prospects of a quick deal on Thursday (local time).
"My argument to the countries that are not willing to accept refugees is that if we can't handle this the European Union is at risk. If we cannot do it there is a risk to Schengen," he said, referring to Europe's passport-free travel zone.
Lofven and Dutch Prime Minister Mark Rutte said Europe had six to eight weeks to find a solution.
Otherwise, border closures could undermine one of the European Union's core principles of free movement, hitting trade and raising questions about the future of the bloc, already threatened by a looming British referendum on its membership.
French Prime Minister Manuel Valls said the refugee crisis and security challenge in Europe posed threats.
"The European project can die, not in decades or years but very fast, if we are unable to face up to the security challenge," Valls told the audience in Davos.
Austria announced on Wednesday that it planned to limit the number of people allowed to apply for asylum to 1.5 per cent of its population over the next four years. For this year, the government said in a statement, the number would be capped at 37,500.
The move raised the risk of a "domino effect" in Europe and piled more pressure on Merkel, who has rebuffed domestic calls for a similar cap, arguing that it would be impossible to enforce without closing borders and tearing apart Europe.
Her Finance Minister Wolfgang Schaeuble called in Davos for "billions of euros" in new money to be transferred to states that border Syria, saying Europe had to realise that solving the crisis would cost "a lot more" than previously envisaged.
Speaking a day earlier however, German President Joachim Gauck, a former East German pastor and dissident who is seen as a voice of morality in Germany, said it was not unethical to limit the influx of refugees, in comments that were seen as an indirect swipe at Merkel's open-door policy.
Austrian Foreign Minister Sebastian Kurz defended the move by Vienna, telling reporters in Davos that his country had not given up on a European solution but simply couldn't afford to wait around forever.
"Some states are being overwhelmed and therefore there is a need to take national measures, but Austria is one of a small number of countries, with Chancellor Merkel in the lead, who are pushing for a European solution," Kurz said.
"At the end of the day, we will do everything to work with her to find a European solution."
