Helsinki-Uusimaa Regional Council has signed partnership agreements with the Mazovia Region in Poland and the Moscow Region in Russia. In June 2014 an agreement was made with the Western Pomerania Region in Poland, and the agreement with the Mazovia Region was made in 2008.
The capital city of Warsaw and the surrounding area belongs to a voivodeship with more than five million inhabitants. Szczecin, the capital of Western Pomerania is a harbour city by the river Oder.
The Helsinki-Uusimaa Region and the Mazovia Region cooperate in regional planning and development, waste management and environment protection, as well as regarding innovations and issues related to a data society. Regional experts meet on a regular basis to exhange experiences. The Stockholm City Council is one of the cooperators.

The latest action programme covers the years 2015-2017. Themes included in the action programme are tourism development, regional planning and infrastructure, water supply and waste water treatment, and agriculture.
