Not surprising since most Russians get their news from Western biased sources. The Western reaction toward Russians in the wake of the invasion came as a shock to many of them.
Which is yet another positive for China. Russians need to be forcibly severed from their western ideas, not by making them physically unable to access them, but by mentally expunging their willpower to pursue such ideologies. What better way to make Russians distrust the west than when they see with their own eyes western media celebrating the death of Russian civilians?
Territories where US state mouthpieces dominate can never be fully trusted to be free from infiltration. Case in point, see HK. Therefore, in the last decade, China cannot sell its most valuable tech to Russia even if Russia begged for it. And Russia could not share most of its own developments with China either.
Whether the war turns into an eventual triumph for Russia or into their Suez crisis moment, China will hopefully have completely expunged Russian nativist (more like: pro-west) elements by the end.
Putin talks much about multipolarity and this is a dangerous word. Multipolarity means acknowledging useless oligarchies that have done nothing for their people and never will as legit entities, and undermines Chinese leadership.
Who knows if this is Putin's genuine thoughts or if it is just a facade to keep middle powers such as India placated. At least, Russia has embarked on this conflict and so, drawn a strict line between itself and the west. And whoever inside Russia was behind it, it shows they are trustworthy.
