I agree that Xi won't take any overt actions to help Ru but pushing hard for a peace deal would not result in Western Sanctions.
It's amazing that Putin can sustain these losses for so long. USSR losr 50K men in over 10 yrs in Afghanistan and this caused unrest at home, ultimately leading to withdrawal.
Just shows Putin's absolute control of the Information Space - he's been able to spin this as a victory so far, reporting that Ua casualties are far more than his own.
But I agree with you, it's not sustainable in the medium term - he is recruiting from Africa now but these guy are pretty useless as they have no training or experience. His equipment losses means he'll hit the wall here too, before long.
