Celebrating the achievements of European regions and countries working together across borders. That is what is behind European Co operation Day which for the first time will be marked on the same day across Europe, both in EU member states and neighbouring countries.
Speaking from the European Parliament in Brussels to launch more than 200 events in 40 countries, the EU's Commissioner for Regional Policy Johannes Hahn said: "Territorial cooperation projects help build trust. They foster mutual understanding. They are essential ingredients of European integration. They bring communities together – this is the European Union in action".
