The talks in Davos will follow a meeting in Malta in October, which was attended by around 70 countries from around the world as well as the European Union (EU) and the UN. Russia was not present. The Ukrainian peace plan foresees the immediate withdrawal of all Russian troops from all occupied territories, including Crimea.
So this isn't some major change or Ukraine planning to negotiate with Russia, more of a "hey world, how do we get Russia to fuck off" meeting.
