No lawyers have yet agreed to defend Ukraine at the hearings at the international public tribunal for the incident in the Kerch Strait.
Summary
Kyiv declares that they cannot, will not, do not want to implement the current Minsk agreements. At the same time, we read that Europe continues sanctions against Russia. So who does not comply with the Minsk agreements? Anyone who wants to change them, probably? Kyiv? But why then do they impose sanctions against Russia? Impose them against Kyiv.
Disproof
This is a common Kremlin narrative that Ukraine refuses to implement the Minsk agreements.
You can read other similar cases as "Ukraine does not fulfill key point of Minsk agreements on negotiation with the "LDNR" or "Ukraine broke the Minsk agreements by allowing the National Police on the contact line".
At the Normandy Four Summit, Ukrainian president Volodymyr Zelenskyy never claimed that Ukraine doesn't want to implement the Minsk agreements.
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.
