It's not coming out of nowhere. The proximate cause of the Maidan revolution, lest we forget, was Yanukovych's last-minute refusal to sign the EU association agreement, preferring instead to put his country in hock to Russia.
The European Union-Ukraine Association Agreement is in force since 2017.

The agreement commits Ukraine to economic, judicial, and financial reforms to converge its policies and legislation to those of the European Union. Ukraine commits to gradually conform to EU technical and consumer standards.[6] The EU agrees to provide Ukraine with political and financial support, access to research and knowledge, and preferential access to EU markets. The agreement commits both parties to promote a gradual convergence toward the EU's Common Security and Defence Policy and European Defence Agency policies.

Accelerating the process is an absolute certainty after recent events. Chalk up a victory for Vlad.
