Ukraine Opens Second EU Negotiating Cluster as Reform Delivery Shapes Further Accession Progress, KSE Institute Says

Ukraine Opens Its Second Negotiating Cluster, but Further EU Accession Progress Depends on Reform Delivery – KSE Institute In Q3 2026, Ukraine continued to advance in its EU accession negotiations. On July 14, Cluster VI, “External Relations,” was formally opened, becoming the second open cluster. As of September 16, two of six negotiating clusters and seven of 33 chapters had been opened. At the same time, measurable progress in negotiations and legislation contrasted with slower delivery on rule-of-law commitments, according to KSE Institute’s Ukraine EU Accession Tracker for Q3 2026.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. Hungary did not approve the opening of Cluster II, “Internal Market,” and Cluster III, “Competitiveness & Inclusive Growth.” Following the July government change, nine Ukraine Facility-linked bills were removed from the Verkhovna Rada’s agenda; seven have since returned, while two still have no replacement. The new government nevertheless remains committed to opening all six negotiating clusters and completing negotiations by the end of 2027. Progress on rule-of-law commitments remains slow. Only one of the ten points in the Kachka–Kos plan has been fully completed. Six of the 11 priority laws identified by EU Enlargement Commissioner Marta Kos have been adopted and signed, while two more are awaiting signature. Reforms concerning NEURC independence, state-aid control, and the restoration of civil-service competitions remain incomplete.

Two of the EU’s three financing tracks are conditional on reform delivery. The Macro-Financial Assistance track totals €8.35 billion, but the next €3.7 billion installment has been delayed until at least Q4 because some conditions were not met by August 31. Following the revision of the Ukraine Facility, its total payment envelope increased to €40.9 billion, with 27 new reform steps added. As of mid-September, Ukraine had received €21.6 billion in seven Ukraine Facility installments, while €1.7 billion from previous payments had been withheld due to unmet commitments. The €28.3 billion Ukraine Support Loan for defence is not conditional on reforms; €8.4 billion has already been disbursed. The further pace of accession will increasingly depend on completing prosecution and anti-corruption reforms, key legislative changes, and the conditions tied to European financing.
