This was stated by U.S. special representative for Ukraine Kurt Volker, Censor.NET reports citing Financial Times.
He warned that Russia was "going to have to make some fundamental decisions" on whether to comply with the Minsk accord aimed at bringing peace to east Ukraine and pull its forces out of the region.
"A situation where Russia is going to be frozen out of diplomatic relationships, of economic relationships, because of this, is certainly not something that Russia would want. I think they have got to make their own choice, their own calculations," Volker stressed.
Citing discussions with Ukrainian, European and Russian officials, he said all agreed that the Minsk process was "not going anywhere". The US was trying to "give an impetus to the process", he said.
But he put the onus for breaking the deadlock on Moscow, adding: "Russia has forces in eastern Ukraine and it needs to pull them out."
