- "This is Russia’s attempt to legitimize its illegal military control and aims to forcibly change Ukraine’s borders in clear violation of the UN Charter and Ukraine’s independence, sovereignty, and territorial integrity," said the High Representative of the European Union for Foreign Affairs and Security Policy Josep Borrell in a statement. He noted that the results of referendums would be null and void and would not be recognized by the EU and its Member States.
 
- The US will continue to stand with the people of Ukraine, the United States Secretary of State Antony Blinken said. "If Russia does stage these sham “referenda”, the United States and the international community will never recognize Russia’s claims to any purportedly-annexed parts of Ukraine."
 - Canadian Prime Minister Justin Trudeau also condemned the "referendum" in occupied territories. "Canada denounces Russia’s planned “referendums” in occupied regions of Ukraine. We will never recognize them. This is a blatant violation of international law. It is a further escalation of the war. And it is unacceptable."
 - "Sham referendums have no legitimacy and do not change the nature of Russia’s war of aggression against Ukraine. This is a further escalation in Putin’s war," Secretary General of NATO Jens Stoltenberg stated. He called the international community to condemn the blatant violation of international law and step up support for Ukraine.
