Debica is the initiator of international cooperation of towns from all countries of European Union. At present following towns are involved in this cooperation: Puurs from Belgium, Kapuvar from Hungary, Obzor and Svishtov from Bulgaria, Carei from Romania, Salo from Finland, Muro on Majorca and Dunaujvaros from Hungary. The idea of the wide cooperation is also concerned with economy.
Since 1999 Debica cooperates with Belgian town Puurs. Multilateral cooperation of Debica and Puurs is promoted by local authorities, cultural centers, town organizations and schools.
Ties between the towns interested in cooperation within „Europe of the Towns” programme are still being tightened, and Debica was initiator of this project. It is based on the idea of direct cooperation with towns from European Union, at least one from each member country. Within this programme residents can use cheap tourist offers, get to know the culture of member countries, establish industrial and economic links, present their companies in other countries.
Debica is involved in active cooperation with neighbouring towns to improve living conditions, modernise infrastructure and protect environment.
