In a release issued after the meeting, the office of the UN secretary general said the meeting was about the latest developments in the Western Balkans, including the refugee and migration crisis.

Ban called for a unified European response to the crisis and reiterated the United Nations' support in facing with the challenges, according to his office.

The UN secretary general also congratulated Slovenia on its chairmanship of the UN General Assembly's Second Committee (economy and finance) during the 70th session.

Cerar's office also said that the secretary general enquired about Slovenia's view of the situation in the Western Balkans, where the UN had noticed certain tensions.

Cerar confirmed that the situation was somewhat tense, suggesting Montenegro's accession to NATO as one of the solutions that could contribute to a stabilisation.

Ban called for implementing global solidarity in the relocation of refugees and migrants, while he and Cerar agreed they must be treated humanely.

The prime minister was interested in Ban's views on the resolution of the Syrian crisis and was told that Ban was continuously in contact with members of the UN Security Council and was urging their cooperation.

Before the meeting, Cerar told Slovenian reporters in New York it was premature to say whether progress had been made over the resolution of the Syria crisis during the world leaders' meetings in New York.

"I do believe there's progress in the Americans and Russians talking to each other. Despite the differences between them, fact is that neither Europe nor any of the great powers can resolve the crisis alone."

Cerar added that the general debate at the 70th session of the UN General Assembly was a proper forum to find an answer where the leaders of great powers could also give an ear to other countries.

"Slovenia hasn't remained unnoticed. Our opinion was heard and we are on the world map. I believe we can also operate this way in the future. It has become clear the crisis must be solved and I believe we are at a turning point. I'm confident the matter will now get intensified."
