The study will focus on the European Union’s attitude towards Russia by taking into consideration a dilemma: The European Union (EU) wants to uphold its values and principles while endeavoring to maximize its interests. In the post-Cold War period, Moscow’s policy choices have often been problematic for the Europeans. In the period following the Ukrainian conflict, the analysis of the relations between the two “strategic partners” is more difficult than ever. At least three reasons underlie this difficulty. First, the EU is notoriously incapable of reaching a common position on how to deal with the Russian problem. Second, trade is an important factor for the relations between the EU and Russia where oil occupies a significant place. Third, Russia has also a signification position vis-à-vis the EU as a powerful actor of international relations.
