This is a common pro-Kremlin narrative that Ukraine refuses to implement the Minsk agreements.

At the end of January 2020, the Parliamentary Assembly of the Council of Europe adopted a resolution on the status of the monitoring procedure, where Russia was named as a “party to the Minsk agreements”. The PACE resolution noted that the Russian authorities should, among other things, “fully implement the Minsk agreements to which the Russian Federation is a party and to end its military intervention in, and support for, illegally armed formations in Eastern Ukraine."
Since 2014, negotiations with Russia to resolve the conflict in the Donbas have been held within the framework of the Normandy Format and the Minsk process. A special Trilateral contact group is working on a peaceful settlement of the situation in Donbas. Three parties are involved in this process: representatives of Ukraine, Russia and the OSCE. Unofficially, representatives of the "LDNR" factions are also present.
The second set of measures to implement the Minsk agreements was signed on 12 February 2015. The first paragraph of the document relates to an immediate ceasefire. Next, it is necessary to withdraw heavy weapons, ensure OSCE monitoring, release prisoners, grant Donbas special status and hold local elections, provide amnesty to the parties involved in the conflict and restore control over the Ukrainian-Russian border in the conflict zone. There are no conditions that the Ukrainian authorities should conduct direct negotiations with the leaders of the "LDNR" factions in the Minsk agreements.
