Ukraine Now Negotiates EU Accession While Fighting a War—Something Europe Has Never Done

The EU opened its first substantive accession cluster with Ukraine on 12 June 2026. Unlike past candidates, Ukraine must harmonize laws across 35 policy chapters—competition, environment, judiciary—concurrent with active armed conflict. The Commission has acknowledged this requires procedural adaptation, but the formal framework remains incomplete. Timeline to full accession remains undefined; negotiations typically extend years.
