EU Enlargement Commissioner Marta Kos has delivered a firm response to the proposal by Serbian President Aleksandar Vučić and Albanian Prime Minister Edi Rama for an alternative, “staged” integration into the European Union.
Speaking at the University of Freiburg on April 30, with reports circulating on May 1, 2026, Kos dismissed the idea of gaining access to the European Single Market and the Schengen Area without first fulfilling the rigorous requirements of full EU membership.
The “No Discounts” Policy
The initiative, recently published by Vučić and Rama in the Frankfurter Allgemeine Zeitung, suggested that the EU should allow Western Balkan nations to join its economic and travel zones as a halfway house to full membership. Commissioner Kos was unequivocal in her rejection:
- No Halfway House: “There is no ‘membership light,’ no half-membership; there is only full membership or nothing,” Kos stated.
- Rule of Law is Non-Negotiable: She reminded the leaders that access to the Single Market and Schengen requires the same standards of judicial independence and the rule of law as full membership.
- Role of the Commission: While acknowledging internal EU debates on “gradual integration,” she emphasized that her mandate is strictly to prepare countries for full integration.
Serbia’s “Backsliding” and the Geopolitical Choice
The Commissioner expressed deep concern regarding Serbia’s current trajectory, noting that the country is regressing in key areas essential for accession.
The “Two Chairs” Dilemma:
Kos reiterated the long-standing EU demand for geopolitical alignment, particularly regarding Russia and security policy.
“You cannot sit on two chairs. At some point, Serbia will have to decide what is most important for its development. Before becoming a member, a country must be 100% aligned with the EU’s foreign and security policy,” she noted.
Areas of Regression identified by the Commissioner:
- Democratic Values: Significant polarization and a lack of democratic accountability.
- Fundamental Freedoms: A sharp decline in the freedom of speech and, specifically, the freedom of the media.
- Judicial Reform: Failure to implement recommendations from the Venice Commission.
Financial Consequences: Funds on Hold
The Commissioner’s rhetoric is backed by financial pressure. The EU is currently withholding significant funds from Serbia, waiting for concrete evidence that Belgrade is fulfilling its commitments.
| Current Status | EU Position |
| Financial Support | Funds remain on EU accounts; payout depends on rule of law progress. |
| Pre-Accession Aid | Risks being frozen if Serbia is categorized alongside Turkey and Georgia as a “formal candidate” only. |
| Expectations | Brussels is looking for “results, not just nodding heads.” |
Analysis: A Shift in Tone
Marta Kos’s comments represent a hardening of the EU’s stance in 2026. By explicitly calling out “backsliding” and rejecting “creative” alternatives to the accession process, Brussels is signaling that the era of “stabilocracy”—where stability was traded for democratic standards—is over. For Vučić and Rama, the message is clear: the road to Europe leads through domestic reform, not through bypassing the Copenhagen Criteria.
