Without such a policy the crisis will be a very tough challenge for individual countries, including Slovenia.

Commenting on Hungary's efforts to keep refugees out of the country, Pahor said that he told "Orban openly that I was left speechless in the face of some of his assessments". He added that Hungary's decisions will however have to be taken into account.

Talking to the press after the meeting, Pahor said that the refugee crisis was just as complicated as the financial and economic crisis. "We can only overcome it together."

Unless the EU makes progress toward a joint migration policy, many countries, including Slovenia, will find themselves in a very tough situation, said Pahor.

"It will be exposed to a big wave of refugees and this will be a very tough challenge, despite our determination to face it in the most humanitarian and humane way," said the president.

He noted that the Hungarian decision to close the border would divert refugee flows and expressed concern over Hungary's plan to promote that the Visegrad Group adopts a position similar to its own.

This would in effect undermine any attempts for a joint refugee policy of the EU, which is a great concern for Slovenia, Pahor said.

"But worrying will not resolve problems. The only thing that does help is being well-prepared in time," said the president, adding that he is to meet Prime Minister Miro Cerar, Interior Minister Vesna Györkös Žnidar and others to discuss appropriate measures.

Pahor met Orban after meeting President Janos Ader on Thursday. The presidents urged a single refugee policy on the level of the EU.
