The Ukrainian side claimed that the Minsk agreements are just a piece of paper and they are not necessary for implementation. Therefore Russia could claim as well that there’s no need to fulfill these agreements. Or is it only the DPR-LPR that should fulfill them? If this agreement is optional, then could the DPR-LPR attack too?
Crimea returned to Russia after a referendum on the peninsula.
Recurring pro-Kremlin disinformation narrative about the annexation of Crimea, claiming that Crimea voted to rejoin Russia through a legal referendum.
Crimea is a part of Ukraine and was illegally annexed by Russia. In 2014, Russian troops obliged the parliament of Crimea to organise a referendum, which was illegitimate under international law, and then formally annexed the peninsula and brought it under Russian territorial control. The annexation has been condemned by the UNGA (see the resolution A/RES/68/262 on the territorial integrity of Ukraine).
No international body recognises the so-called referendum, announced on 27 February 2014 and held on 16 March 2014.
Following the covert invasion by “little green men,” the referendum in Crimea was conducted hastily and at gunpoint, barring impartial observers from entering the peninsula.
A year after the illegal annexation, Russian President Vladimir Putin admitted that the plan to annex Crimea was ordered weeks before the so-called referendum.
The European Union does not recognise Crimea's annexation and continues to condemn it as a violation of international law. EU sanctions continue to be in place against Russia as a consequence for the annexation. For the EU statement on the sixth anniversary of Crimea annexation see here.
