When asked about Russia's interest in federalizing Ukraine, U.S. Secretary of State John Kerry responded that such a decision would be made by Ukraine itself.
"It’s not up to us to make any decision or any agreement regarding federalization. We talked about it. But it’s up to Ukrainians, and Ukrainians will decide their future for themselves, by themselves, with respect to what kind of definitions work for them. And it will have to be an input, obviously, of what the Russian view is. I think it’s important to take that into account because Russia obviously has long ties and serious interests. But in the end, Ukrainians are going to have to make that decision."
