For an internationally oriented and at the same time solidary city like Zurich, the cultivation of international contacts and cooperation is of great importance. The city benefits from the exchange of knowledge and experience, for example within the framework of city networks, temporary thematic cooperations or through participation in European projects. It can make an important contribution to global sustainable development, including through the city partnership with the Chinese city of Kunming. In view of the dramatic refugee situation, the city can also make an important humanitarian contribution as part of the "First Flight City" project.
