The sad fact is that while Russia keeps making active steps, EU only gets "concerned", but nothing more... It is time for EU to do some real actions (not sanctions...). They should propose some real alternative options, even for Yanukovich - maybe a full EU membership or something similar, bit more than just Association Agreement.
If it was Bosnia or something with a small population, it would be doable. It's political and economic suicide for the EU to offer full membership on a whim like this.
