Politics of Berlin - Sister Cities

Sister Cities

Berlin maintains official partnerships with 17 cities. Town twinning between Berlin and other cities began with Los Angeles in 1967. East Berlin's partnerships were canceled at the time of German reunification and later partially reestablished. West Berlin's partnerships had previously been restricted to the borough level. During the Cold War era, the partnerships had reflected the different power blocs, with West Berlin partnering with capitals in the West, and East Berlin mostly partnering with cities from the Warsaw Pact and its allies.

There are several joint projects with many other cities, such as Belgrade, Copenhagen, Helsinki, Johannesburg, Shanghai, Seoul, Sofia, Sydney, and Vienna. Berlin participates in international city associations such as the Union of the Capitals of the European Union, Eurocities, Network of European Cities of Culture, Metropolis, Summit Conference of the World's Major Cities, Conference of the World's Capital Cities.
