The European Union has been compelled to recalibrate its enlargement strategy for Ukraine and Moldova, acknowledging that only two of the five planned accession clusters are likely to be opened before the summer parliamentary recess. The revision follows sustained opposition from Budapest, which has leveraged its veto power within the Council to slow the process.
Diplomats in Brussels confirmed that the original ambition to advance on five clusters—covering fundamental reforms, the internal market, and justice and home affairs—has proved unworkable given Hungary's blocking tactics. The new target focuses on the most politically palatable chapters, though even these remain contingent on further negotiations.
Hungary's Veto as a Strategic Tool
Prime Minister Viktor Orbán's government has consistently linked Ukraine's accession to the rights of the Hungarian minority in western Ukraine, a demand Kyiv has partially addressed but not fully satisfied. Budapest has also used the enlargement file as leverage in unrelated disputes with Brussels over rule-of-law conditionality and frozen funds. The result is a slowdown that threatens to undermine the EU's credibility as a security anchor for Eastern Europe.
“The EU cannot afford to appear weak on enlargement when Russia is waging a war of attrition against Ukraine,” said a senior EU official speaking on condition of anonymity. “But unanimity rules mean one member state can hold the entire process hostage.”
The scaling back comes at a delicate moment. Ukraine has made significant progress on anti-corruption reforms and judicial independence, but the EU's inability to deliver on its promises risks feeding disillusionment in Kyiv. Moldova, meanwhile, has accelerated its own reform agenda, though its path may diverge from Ukraine's, as Brussels has signalled that Chisinau's progress could be assessed separately.
Broader Geopolitical Context
The delay also coincides with heightened tensions between Poland and Ukraine over grain imports and historical grievances. Berlin talks have sought to mend the rift, but the spat has played into Russian narratives about disunity among Ukraine's supporters. Brussels has warned that such infighting benefits the Kremlin.
On the battlefield, Ukraine continues to degrade Russian logistics, most recently destroying a key railway bridge in Crimea. But diplomatic progress on the EU front remains stalled, highlighting the gap between military resilience and political integration.
EU leaders are expected to revisit the enlargement roadmap at the June European Council, though few expect a breakthrough. The bloc's enlargement methodology, revised in 2020, allows for reversibility and phased accession, but it cannot circumvent the unanimity requirement. As a result, the EU's eastern flank may have to wait longer than anticipated for the institutional embrace that many in Kyiv and Chisinau see as existential.
For now, the revised timetable reflects a sobering reality: the EU's transformative power is constrained by its own internal politics. The question is whether Ukraine and Moldova can sustain their reform momentum without the immediate reward of accelerated accession.
