EU Rewards Meet Balkan Crises

Between Dec. 9-18, the EU-Western Balkans Summit and the Brussels Declaration framed political dynamics in the Western Balkans. Brussels used the moment to restate that the region’s EU track is conditional: rewards follow de-escalation and reform, but they remain provisional.

Kosovo benefited as the EU lifted 2023 sanctions and moved to release $253 million before the Dec. 28 snap election. Montenegro advanced on its EU membership path by provisionally closing five more accession chapters, but the toughest rule-of-law tests remain.

But while Brussels rewarded progress in Kosovo and Montenegro, Albania and Serbia revealed a tougher terrain with corruption cases and contested mega-projects turning into open political conflict.

The EU may try to govern through incentives, but the region’s fault lines are domestic: state capture, corruption, and public backlash. These fights will decide whether the region consolidates toward EU standards or stays stuck in recurring crises that outsiders can exploit. 

Kosovo 

On Dec. 18, the EU moved to lift the measures imposed against Kosovo in 2023 after Prime Minister Albin Kurti failed to diffuse unrest in the country’s north that left 30 NATO peacekeeping troops injured. The EU's move comes with $253 million in financial assistance set to be released in early 2026. Brussels explicitly tied this policy reversal to de-escalation and political changes in northern Kosovo, as four Serb mayors were inaugurated following the October elections.

The timing of Brussels’ policy reversal matters. Kosovo heads into Dec. 28 snap parliamentary elections after a prolonged government-formation failure that subsequently stalled the state budget, so the EU’s decisions simultaneously function as economic relief and an instrument shaping political authority and conditions of governability in Kosovo’s north.

By rewarding a specific type of order – a governance arrangement in northern Kosovo that does not produce security crises – Brussels signals what it expects “normalization” to look like, and that Kosovo’s European path will be judged on its capacity to govern contested territory without escalation. 

Montenegro 

On Dec. 16, Montenegro provisionally closed five more negotiating chapters on its path to EU membership and consolidated its position as a frontrunner in the Western Balkans’ EU trajectory.

This move fits the EU’s preferred enlargement script: gradual progress and technical wins that signal geopolitical resolve and keep the promise of accession alive without committing to near-term membership.

But the provisional label raises the credibility bar: the EU explicitly retains the option to return to these chapters if implementation slips, so Montenegro must now demonstrate concrete implementation. In practice, this means that Montenegro must translate episodic compliance into durable institutional transformation, ranging from agriculture and fisheries to company law, free movement of capital, and rights and freedoms in business services.

Montenegro is becoming the EU’s main test case for whether enlargement still works as a tool of change. If these chapter closures do not translate into visible and sustained improvements, Brussels’ promise of “credible enlargement” will look hollow to the rest of the region. If Montenegro does deliver required reforms, it strengthens the opposite message: that the EU track can still discipline governance and produce concrete outcomes. 

Albania 

Following the rapid opening of all negotiating clusters over the last year, Albania’s next steps include securing the Interim Benchmark Assessment Report (IBAR) for negotiating Cluster 1, which will allow it to formally start closing chapters. This will require tangible reforms in consolidating democratic institutions, strengthening the judiciary, fighting corruption, and ensuring media freedom that extend beyond mere adoption of law. 

Challenges persist. Internally, high-level corruption scandals, coupled with a strong executive set against a perceptually weaker judiciary, are sharpening into a political confrontation that risks stalling progress and endangering Tirana’s status as one of the “frontrunners” for accession.

Despite internal turmoil, Albania serves as a vital partner for the EU as its committed, pro-Western stance counterbalances other regional actors increasingly disillusioned by Brussels’ promises. Thus, ensuring Albania’s success is just as important for the EU in providing legitimacy and securing Europe’s broader geo-security imperatives as it is for advancing Albania’s own goals.  

Serbia 

Serbian President Aleksandar Vučić declined to send representation to the EU-Western Balkans Summit, claiming to be protecting Serbian interests and dignity amid stalled negotiations that unjustly demonstrate the EU’s lack of recognition of Serbia’s progress.

Yet, the boycott does not mean Belgrade has completely abandoned its accession efforts. Rather, it highlights its confidence in negotiating. On Dec. 10, during a dinner with President of the European Commission Ursula von der Leyen and President of the European Council Antonio Costa, Vučić proposed that the entire Western Balkans join the EU simultaneously as a means to promote regional stability and cooperation.

Essentially, Vučić’s appeal would offer Belgrade “free-rider status,” while subsequent abstention from the Summit signal deflection of responsibility for Serbia’s lag in reforms. Domestically, contested mega-projects like Jared Kushner's former Yugoslav Army HQ project and Chinese-backed Sava Bridge prompt concerns over transparency, corruption, and foreign investment, generating further public discontent and democratic backsliding.

Like Albania, Serbia's accession is essential for ensuring European security, but Serbia’s multi-vector and geoeconomic maneuverings highlight its willingness to seek partnership beyond the EU. Brussels must come to terms that Belgrade will weaponize its position for calculated gains.

Therefore, when it comes to Serbia, the EU is faced with reconciling Belgrade's desire to maintain strategic autonomy, while preserving the Union’s core values.  

Regional Implications 

Brussels’ message to the Western Balkan states was clear: rewards follow credible reforms. If Kosovo stabilizes its north and Montenegro turns provisional chapter closures into a durable transformation, the EU membership track stays credible. If Albania’s confrontation over corruption hardens into institutional paralysis and Serbia keeps deflecting reform, enlargement will shrink into crisis management with conditional funds and periodic pressure designed to contain instability rather than bring the region into the Union.
