The Kremlin has said that the fighting would end immediately if Ukraine allows Crimea to remain part of Russia, that the country should change its constitution and not enter into any alliances, and that Donetsk and Luhansk in eastern Ukraine should be recognized as independent states.
At the same time, Ukraine comes with demands: It wants to be a sovereign state and get the Russians out of its territory.
- The problem is that in Ukraine they probably do not believe that any promises to Russia are enough.
They are not trusted, says Martin Kragh, deputy director of the Center for Eastern European Studies, referring to Russia's annexation of Crimea in 2014.
Sven Hirdman, former ambassador to Russia, also states that confidence is not great.
"If there is to be a settlement in the future, as Ukraine will not trust Putin, it will require bilateral assurances and guarantees from the EU and other powers," he said.
When it comes to a diplomatic solution, Kragh believes that the time when Ukraine trusts Putin's signature is completely over.
- It may be that they try to find a solution and that Russia withdraws its military, but so far we see the opposite, he says.
