Abstract:
Every EU enlargement signified a step towards Central and Eastern Europe, therefore, the 2004 „big bang enlargement”, followed by the one in 2007, modified the geopolitical context within the „old continent” and also increased the importance of the European Union regionally, as well as globally. Integrating the ex-soviet countries into the EU meant taking them out of the Russian sphere of influence, as well as attempting to super size the EU territory in order to increase the European power on a long term. Despite the weakening of Russia after the Cold War, the federation still represents a challenge regarding „pax europea”, as Russia still has an amazing military capacity, as well as important natural resources. The entrance into the Russian sphere of influence, the European energetic dependency on Russia, the conflicts within the separatist regions situated at the EU eastern borders are just few of the many challenges regarding the relations between the European Union and Russia.
