You forget about the Russian "big brother" - CHINA. The fate of Russia, in fact, depends on the position of China. And if now China decides that it needs Russia, but as a donor of resources or territories, then tomorrow Russia will cease to exist and become a new region of the PRC. Stories about a "strong economy" and the same fabulous "strongest army" of Russia are a myth. The only real threat from the Russian Federation is the remnants of nuclear weapons, everything else is "wearing the clothes of the deceased grandfather", i.e. the USSR
You are forgetting that China is staying away from this war for now because of a reason. If they wanted to get involved then they would have already sent some help to Russia to show their help. However lets assume that they are not right now but they will in case of a sanction, even in that situation do you really think that China would get away with it, without a problem?Obviously they are going to end up with a big problem because China sells all of the cheap manufactured things to nations with money, all those items are going to Europe and the USA, which means if you remove ALL of Europe and USA from Chinese companies then they won't make enough money and as a nation with 1+ billion people, they really need to handle all of this in order to continue living, even a small problem would equal to another 20+ million people dead famine as well.

China has officially confirmed that China supports the territorial integrity of countries in Europe, including Ukraine. And this is not at all a friendly position towards the Russian Federation. Although the Russian Federation has always "boasted" at all corners of its "strong friendship with the fraternal Chinese people." China is smart, China will not support a terrorist state, and will not shove against international laws.
PS. After Putin's speech, the Russian economy, for 1.5. hours lost 1 trillion rubles! This has not yet been imposed sanctions, and Western leaders have not made statements
