The minister pointed to the example of Slovenia and Croatia, saying that the two countries which "cannot find common ground on anything" attended tourism fairs and presentations together, especially in distant markets such as Japan and China.

All other countries in the region could join these presentations, especially those on far-away markets. "Nobody from that areas will come to visit just Slovenia or Croatia," he said.

Počivalšek took part in a panel on the movement of goods and persons in the region, which heard calls for removing all bureaucratic obstacles in this area.

Počivalšek said that removing obstacles to enable free movement of goods and people was extremely important for Slovenia, which is an export-oriented economy. "Obstacle are only in our heads," he said.

A project striving for this is called Balkanika Free Cargo, envisaging a free flow of cargo from Greece to Macedonia and then through Serbia to the EU, while business model Green Balkanika envisages electrification of motorway München-Salzburg-Ljubljana-Belgrade-Skopje-Istanbul.

Both projects were also mentioned at last year's Summit 100 in Portorož, but the migrant wave slowed down the talks on their implementation. An opportunity for further talks will be a business meeting at the Western Balkan summit in Paris on 4 July.

A panel on competitive innovations with sustainable energy sources will be held this afternoon as part of Summit 100, which will wrap up this evening with a debate to be attended by leaders of the Brdo-Bijuni Process regional initiative, including Slovenian President Borut Pahor.
