The Impact of Russia’s Invasion of Ukraine on the Western Balkans and the Transformation of the EU Enlargement Policy
Terézia Hlačinová
Russia’s invasion of Ukraine in February 2022 represents a watershed moment in contemporary European geopolitics. The conflict has not only reshaped Europe’s security architecture but also accelerated a broader redefinition of the European Union’s external relations, particularly in its immediate neighbourhood. While the military confrontation is geographically confined to Eastern Europe, its political, economic, and strategic repercussions have extended far beyond Ukraine’s borders.
One of the regions most affected by these indirect consequences is the Western Balkans, which includes Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia, and Serbia. Incomplete state consolidation, fragile democratic institutions, and a protracted process of European integration have long characterised this region. Despite repeated commitments from the European Union to the region’s membership perspective, actual progress has been uneven and often slow, contributing to political uncertainty and reform fatigue. The war in Ukraine has altered this context by reintroducing security and geopolitics as central drivers of EU enlargement policy. It has also intensified external competition in the Western Balkans, where Russia, China, and Turkey maintain varying degrees of influence. This article analyses how the war has affected political stability, security dynamics, and economic conditions in the Western Balkans, and examines its impact on the European Union’s enlargement strategy. It argues that the conflict has both heightened the region’s strategic importance and exposed the limitations of the EU’s long-term approach to enlargement.

Geopolitical Turning Point and Renewed Strategic Importance
The Western Balkans occupy a geopolitically sensitive position at the intersection of competing regional and global interests. Historically, the European Union has been the primary external actor shaping reform processes in the region through its enlargement policy. Since the Thessaloniki Summit of 2003, the EU has formally acknowledged the European perspective of the Western Balkans. However, despite this commitment, integration has progressed slowly due to a combination of internal EU enlargement fatigue and limited implementation of domestic reforms.

Transformation of EU Enlargement Policy and Security Dynamics
Before 2022, EU engagement in the Western Balkans was largely technocratic and conditionality-based, focusing on democratic reforms, the rule of law, and economic alignment with EU standards. However, the geopolitical environment following Russia’s invasion of Ukraine has shifted this approach. The Western Balkans are now increasingly perceived through a security lens, particularly due to concerns that political instability in the region could be exploited by external actors seeking to undermine EU cohesion. This shift reflects a broader transformation in EU strategic thinking, where enlargement is no longer solely a normative project but also a tool of geopolitical stabilisation. The region has consequently regained importance within EU foreign policy discussions, particularly in relation to energy security, migration management, and countering foreign influence. The war in Ukraine has significantly accelerated changes in the EU’s enlargement policy. The decision to grant candidate status to Ukraine and Moldova, alongside enhanced engagement with Georgia, marked a clear geopolitical turn in EU external relations. This development was interpreted in the Western Balkans as both a signal of renewed EU strategic urgency and a source of frustration due to the comparatively slow progress of long-standing candidate countries.
While Ukraine’s candidacy was fast-tracked due to geopolitical necessity, Western Balkan states have been subject to a prolonged accession process that has often stalled due to internal EU divisions or insufficient reform progress. This divergence has raised questions about the coherence of EU conditionality and the credibility of its enlargement commitments.
At the same time, enlargement has become increasingly linked to security considerations. The EU now views accession not only as a mechanism for democratic transformation but also as a means of preventing geopolitical fragmentation in its immediate neighbourhood. The war in Ukraine has had significant implications for the security environment in the Western Balkans. The region continues to be marked by unresolved political disputes, ethnic divisions, and institutional fragility, all of which create conditions for potential instability. One of the most sensitive areas remains Bosnia and Herzegovina, where internal political fragmentation and separatist rhetoric challenge the functionality of state institutions. The post-Dayton political structure has proven difficult to reform, and external influences have further complicated domestic political dynamics. In this context, concerns about external interference have increased, particularly regarding Russia’s political and informational presence in the region.
Another persistent source of instability is the relationship between Serbia and Kosovo. Despite ongoing EU-mediated dialogue, tensions periodically escalate, demonstrating the fragility of regional normalisation processes. The war in Ukraine has further heightened sensitivities around sovereignty, territorial integrity, and alignment with external powers, indirectly influencing domestic political discourse in both entities. The overall security environment has therefore become more volatile, prompting increased engagement from NATO and the European Union. NATO membership of Montenegro and North Macedonia reflects a broader trend of Euro-Atlantic integration, while other Western Balkan states have strengthened cooperation with Western security institutions. These developments indicate a gradual consolidation of the region’s security alignment, although not uniformly across all countries.
Economic Pressures, External Influence, and Future Outlook
Beyond security implications, the war in Ukraine has had significant economic consequences for the Western Balkans. The region is highly dependent on imported energy, particularly natural gas and oil, which has made it vulnerable to global price fluctuations triggered by the conflict.
Rising energy costs, inflationary pressures, and disruptions in supply chains have collectively strained economic performance. These challenges have been particularly acute in economies with limited fiscal capacity and high dependence on external trade. Small and medium-sized enterprises, which form the backbone of most Western Balkan economies, have been disproportionately affected by increased operational costs and reduced consumer demand.
The European Union has responded by increasing financial assistance and supporting energy diversification initiatives. These efforts include investments in renewable energy infrastructure, regional interconnectivity projects, and measures aimed at reducing dependence on a single external supplier. Nevertheless, structural weaknesses in governance, infrastructure, and investment climates continue to limit the region’s economic resilience.
The economic dimension of the crisis also has political implications. Economic insecurity often reinforces public dissatisfaction and weakens trust in institutions, creating conditions that populist or nationalist actors may exploit. As a result, economic stability and political stability remain closely interconnected in the Western Balkans.
The Western Balkans have increasingly become a space of geopolitical competition among external actors, each pursuing distinct strategic interests. Russia maintains influence primarily through political networks, energy dependence, cultural ties, and media presence. Its engagement is particularly visible in Serbia and parts of Bosnia and Herzegovina, where it seeks to preserve leverage and counterbalance Euro-Atlantic integration. Russian influence is often indirect but can contribute to political polarisation and institutional distrust.
China has expanded its role through infrastructure investment and economic cooperation, primarily under the framework of the Belt and Road Initiative. These investments have provided much-needed capital for infrastructure development but have also raised concerns regarding debt sustainability and strategic dependency. Unlike the European Union, China does not typically attach political conditionality to its investments, which makes its engagement attractive to some governments but controversial from a governance perspective.
Turkey also remains an important regional actor, maintaining historical, cultural, and economic connections across the Western Balkans. Its influence is particularly visible in trade, education, and cultural diplomacy.
The presence of multiple external actors has increased the strategic complexity of the region. It has also strengthened the EU’s perception that the Western Balkans represent not only a development challenge but also a geopolitical arena in which influence must be actively maintained. The invasion of Ukraine has fundamentally altered the geopolitical context of the Western Balkans and reshaped the European Union’s approach to enlargement. The conflict has elevated the region’s strategic importance by linking it more directly to broader European security concerns. At the same time, it has exposed persistent structural weaknesses related to governance, economic resilience, and political stability.
The EU’s response reflects a growing tension between geopolitical urgency and normative conditionality. While the need for stability has encouraged a more flexible and politically driven enlargement approach, this shift raises concerns about the long-term credibility of EU integration standards. The balance between strategic interests and reform requirements will therefore be central to the future of EU-Western Balkans relations.
Conclusion
In the long term, the region’s trajectory will depend on whether the European Union can translate its renewed engagement into a coherent, sustainable enlargement strategy. Failure to do so may result in prolonged instability and increased competition from external actors. A consistent and credible integration process could significantly help consolidate peace, stability, and democratic governance in the Western Balkans. Ultimately, the war in Ukraine has not only reshaped European security dynamics but has also redefined the Western Balkans as a critical test of the European Union’s capacity to function simultaneously as a normative and geopolitical power.
