Western Balkan foreign and security ties with external actors : an arena of geostrategic rivalry for the EU or a local power struggle?

Even though the six Western Balkan countries (WB6) have close political ties with the EU, their alignment with the EU’s Common Foreign and Security Policy (CFSP) has in­creasingly come into focus since the beginning of the Russian war of aggression in Ukraine. The EU should take a differentiated view of the WB6’s political and security cooperation with external actors such as Russia, China and Turkey. Within the WB6, the two "outliers" of Serbia and Bosnia-Herzegovina’s Republika Srpska use their for­eign and security relations with Russia to achieve their own political goals. While Serbia seeks support for its Kosovo policy, Republika Srpska is trying to get backing for its separatist tendencies. The WB6 are not expected to end their cooperation with the aforementioned external actors in the near future. Nonetheless, in today’s shift­ing geopolitical arena, the EU must set priorities that bind the WB6’s outliers to the CFSP.
