Ukraine categorically refuses to implement the Minsk agreements, yet demands Russia fulfill them.
Moscow has repeatedly indicated that the return of Crimea to the motherland of Russia was based on the results of a popular referendum organised on the peninsula in March 2014.
Recurring pro-Kremlin disinformation narrative about the illegal annexation of Crimea. No international body recognises the so-called referendum, announced 27th of February and held less than three weeks later.
On March 27th, 2014, the UN General Assembly adopted a resolution in which it 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. The oft-cited figure of 97% has been contested by the Kremlin’s own Human Rights Council, which estimated that only between 30% and 50% of Crimeans took part in the referendum, of which some 50-60% favoured secession.
