He said this in his speech to representatives of member states of the organization on Tuesday, January 16, an Ukrinform correspondent reports.
"[We have to] remove the paralysis that has let European conflicts fester and freeze. Having started two world wars, and taking into account the resources and capacities available to Europe, it is unjustifiable for conflicts in the region to persist," the UN chief said.
He said that the settlement of these situations in different parts of Europe "requires pushing back the dangerous tide of nationalism, and revitalizing the relevant mediation initiatives." In this regard, he noted that the issue concerned the Normandy Format and Trilateral Contact Group on Eastern Ukraine, the OSCE Minsk Group on Nagorno-Karabakh, the Geneva International Discussions related to Georgia and the "5+2" process on Transdniestria.
According to him, a concerted effort for solutions leading to long-term stability in the Western Balkans is also urgent.
"I urge European leaders to show that the continent can live up to its ideals of shared prosperity and peaceful coexistence," Guterres said.
