The Northern Dimension (ND) was a joint policy between four equal partners — the European Union, Iceland, Norway, and Russia — regarding the cross-border and external policies geographically covering Northwest Russia, the Baltic Sea and the Arctic regions, including the Barents Region. The ND Policy was initiated in 1999 and renewed in 2006. The Northern Dimension addresses the specific challenges and opportunities arising in those regions and aims to strengthen dialogue and cooperation between the EU and its member states, the northern countries associated with the EU under the European Economic Area and Russia. A particular emphasis is placed on subsidiarity, and on ensuring the active participation of all stakeholders in the North, including regional organizations, local and regional authorities, the academic and business communities, and civil society. On 24 September 2025, the EU, Iceland, and Norway decided to terminate Northern Dimension cooperation with Russia after having suspended it in 2022 after Russia’s invasion of Ukraine.
