The city of Malmö supported Vaasa significantly during the difficult times of the early 1940s. That’s why Vaasa still has Malmöntalo, which has housed a daycare center since 1959, and Malmönkatu even today.
Morogoro (Tanzania) is a twin town. In 2008, Vaasa signed a cooperation agreement with Bellingham in the US state of Washington, which then developed into the so-called Sister City Agreement in 2010. There is also a cooperation agreement with Aunus (Russia) in the field of culture and education. In addition, the city of Vaasa has signed a memorandum of understanding with the Chinese province of Rudong on November 24, 2016, and with Zhenjiang in 2017. The purpose of the memorandum of understanding is to promote trade connections between the regions.
