I don't think it is necessary since everyone agreed that what took place in Mariupol on May the 9th was a turning point making the partition the most likely outcome. The culture gap and shock reached with that military offensive on WW2  civilian parades an unprecedented scale best illustrated with "PRESIDENT OF RUSSIA VLADIMIR PUTIN: Good afternoon, colleagues. Welcome to the Moscow Kremlin.

We are meeting today on the eve of Victory Day – a very special holiday for all of us.

In the years of the Great Patriotic War, our fathers and grandfathers together routed Nazism - an evil and merciless foe.  They defended their homeland, maintained its sovereignty and independence and freed Europe from slavery and violence. We paid dearly for the victory of May 1945, and we will always cherish the memory of those who gave their lives for their country’s freedom, we will cherish their heroism, unity and solidarity in the struggle against a common enemy." (Full text here), no one was representing Ukraine at this table regardless of today's difficulties while a significant part of Ukraine was associating themselves with every word said on this occasion, the following day, parades celebrating faced armoured vehicles and gun fire from those that do not celebrate that day that they see as a defeat setting the future course of events.
The May 25th Ukraine Presidential election was May be a last opportunity if a candidate with a lot of wisdom was elected and able to reverse all the damage done, strong enough to say that Ukraine is no ground for some sort of pay back for Abkhazia and Ossetia, only the long term interests of all communities of Ukraine are considered but the last few days show there is no wisdom at all, the worse is the most likely. Although at least the OSCE report on Transnistria will hopefully produce some results.
