Crimea joined the Russian Federation through a referendum
Recurring pro-Kremlin disinformation narrative on the annexation of Crimea claiming that Crimean citizens chose to rejoin Russia through a legal referendum.
No international body recognises the so-called referendum and held on 16th of March 2014.
On the 27th of February 2014, when it was announced, the UN General Assembly adopted a resolution which stated that the referendum in Crimea was not valid and could not serve as a basis for any change in the status of the peninsula.
A year after the illegal annexation, even the Kremlin admitted that the plan to annex Crimea was ordered weeks before the so-called referendum.
Five years after the illegal annexation of the Autonomous Republic of Crimea and the city of Sevastopol by the Russian Federation, the EU issued a statement in which it confirms its commitment to Ukraine’s sovereignty and territorial integrity and reiterates that it does not recognise and continues to condemn this violation of international law.
