About International cooperation

The City of Oslo is increasingly involved in different types of international cooperation. This includes hosting international events and meetings, participating in international organizations and networks, and partnering in EU-projects.

The International Office is responsible for the overall coordination of Oslo's international cooperation, including coordination of the work of the city departments, agencies and districts. The City’s international work stems from a strategic plan adopted by the City Council.

The Oslo Region European Office is the eyes and ears of the International Office in Brussels.  It is a valuable source of information and helps facilitate contacts between Oslo and the EU.
