Cluster 6 "External relations" opens
One month after Fundamentals, the EU opened a second negotiating cluster with Ukraine — External relations (Cluster 6), comprising chapter 30 (external relations: the common commercial policy, humanitarian aid and development cooperation) and chapter 31 (foreign, security and defence policy, including alignment with EU positions, declarations and sanctions). The EU set benchmarks for the future provisional closure of both chapters. Ukraine's strongest area (external relations and CFSP are its best-prepared chapters), opened out of numerical order while clusters 2–5 remain to be agreed.

Cluster 1 "Fundamentals" opens
At the second EU–Ukraine Accession Conference (Intergovernmental Conference) in Luxembourg, the EU opened the first negotiating cluster, Fundamentals, with Ukraine. Five chapters were opened: 23 (judiciary and fundamental rights), 24 (justice, freedom and security), 5 (public procurement), 18 (statistics) and 32 (financial control). The cluster opens first and closes last, setting the pace of the whole negotiation.

Government target: sign the Accession Treaty in 2027

- Position
Government target: conclude accession negotiations by end of 2028
The government of Ukraine states a goal of concluding accession negotiations by the end of 2028. This is a political target, not a fact. Independent analysts assess membership as more plausibly around 2030 or later.

A member-state veto kept accession talks blocked
