At the June 2021 Brussels Summit, NATO leaders reiterated the decision taken at the 2008 Bucharest Summit that Ukraine would become a member of the Alliance with the Membership Action Plan (MAP) as an integral part of the process and Ukraine's right to determine its own future and foreign policy, of course without outside interference. NATO Secretary General Jens Stoltenberg also stressed that Russia will not be able to veto Ukraine's accession to NATO, as we will not return to the era of spheres of interest, when large countries decide what smaller ones should do.
