Russian–European Union relations are the international relations between the European Union (EU) and the largest country in Europe, Russia. The relations of individual member states of the European Union and Russia vary, though a 1990s common foreign policy outline towards Russia was the first such EU foreign policy agreed. Furthermore, four European Union-Russia Common Spaces are agreed as a framework for establishing better relations. The latest EU-Russia strategic partnership was signed in 2011, but it was later challenged by the European Parliament in 2015 following the annexation of Crimea and the war in Donbas.Russia borders five EU member states: Estonia, Finland, Latvia, Lithuania and Poland.
