China isn't giving them the sideeye lol. What makes you think that?
Take a look at Chinese state media. Notice what's missing? The entire coverage of the war. The CCP might have offered some empty words of condemnation but they're most definitely quietly supporting the war on the side. I have it on good authority that most of Weibo normies are blaming the US for "recklessness".
Chinese companies are currently all scrambling to fill the once-in-a-lifetime opportunity to fill the void left by western sanctions.
Russian banks are already in talks with integrating more closely wtih CIPS to facilitate trade, and to replace Visa/Mastercard with Unionpay.
Don't let your Western bias fool you. To most people in shithole bumfuckistan, this is Russian domestic affairs. Western preening and sanctions over it has only increased suspicions that it, too, might be directed at them in time.
