1) can never become "allies" unless they both are threathened by another more powerful/aggressive superpower-- for the same reason that China and the US could never have been "allies" in the 1970's but for the aggressive foreign policies of the former USSR.
2) The signs so far show that Russia is getting better both economically and militarily with the progression of the Ukraine war. The Asian Times posts that I have posted on this forum offer sufficient evidence.
3) Both the US and China are benefiting from that war. There are also reports that some German companies are moving to China because of the rising energy price back home, etc. The real losers are Ukraine and Europe.
Russia, while paying a heavy price in the war, is mannaging pretty well. If not, China should consider giving help, but right now that seems unnecessary.
4) Despite the fact that you want peace in Ukraine and China says that it wants peace too, there is no common ground on which Russia and US/Ukraine can meet. This alone will kill any possibility of your wish coming true. Let us wait and see.
The trend that things are developing in Ukraine and Gaza don't seem to work against China's interest for now. And I don't think China can do much about them without both sides in each of these conflicts also have the intentions to resolve the conflicts.
