The meetings come as Europe looks increasingly divided over how to deal with the influx of migrants and refugees, mostly coming from civil war-torn Syria. Most migrants are entering the region via Turkey on land, or via Greece, Italy and the Balkans having traveled by boat.
Thousands have drowned attempting the sea crossing, swaying public opinion in favor of allowing refugees in to Europe but the sheer volume of migrants coming into the region is pressuring the authorities and governments facing the challenges involved in re-locating and integrating migrants.
Making matters worse, eastern European countries are also up in arms about a scheme agreed last September to relocate 160,000 migrants. On Wednesday, Hungary announced that it would hold a referendum on whether to accept compulsory EU quotas for relocating migrants.
Opposing the quota system, Prime Minister Viktor Orban said they threatened to "redraw Europe's cultural and religious identity." He is not alone in opposing the quotas with several of Hungary's eastern European neighbors, Poland and the Czech Republic, also opposing the scheme.

Meanwhile Greece, which stands at the frontline of the crisis, is showing signs that it can no longer cope with the influx especially as migrants are turned back from border checks in other countries effectively stranding them in Greece.
On Wednesday, Greek Prime Minister Alexis Tsipras said his country risked turning into a "permanent warehouse of souls" and threatened to block future EU agreements if other member states do not share the burden.
