Orbán said the stronger the cooperation between countries in Central Europe, the stronger their voices will be.

He added that the situation in Europe has changed: "A few years ago, we thought the economies in Central Europe couldn't function without the ones in the West. That may still hold true today, but with the codicil that Western European economies cannot function without the ones in Central Europe."

Orbán said the ethnic Hungarian and Slovenian minorities living in the region are a resource, not a source of conflict, and contribute to a stronger Slovenia and a stronger Hungary.

He said Slovenia can count on a friendly investment environment in Hungary, adding that Hungary is now the seventh-biggest foreign investor in Slovenia, but "wants to advance to the third or fourth place".

Jansa said the agreement is a "bridge to broader cooperation" between the two countries.

It has been 30 years since the first such agreement was signed, on protecting the ethnic minorities in the crossborder region, he added.

The new agreement allocates an annual EUR 10 million for developments in the Mura-Raba region in 2022-2026.
