With the war proving the ineffectiveness of Russian arms industry while separating the west and Russia irreversibly, it fully opens the door for limitless cooperation.
Russia needs Chinese arms and tech on an industrial scale. Russia's best and brightest can contribute to China's own cutting edge industries, where their talents will not be wasted by a capitalist system.
Such changes will further shore up the security and advancement of the socialist project.
Russia can be China's Canada+Japan. the key is going to be selling them tools, and Russian using those tools to be independent, while establishing Chinese tools as the de facto standard in Russia. The key is to control the tools, not the market. TSMC for instance has the market, but no tools. Guess what happens when those with the tools asks TSMC for anything? They bend the knee because they know market goes to 0 without the tools.
Imagine Russia with Chinese machine tools, industrial robots, 5G, semiconductor equipment, etc. making vehicles, airplanes, power chips, etc. and mining, smelting, etc. All of it has a Russian brand name and Russia gets the export market in raw materials/final goods that China doesn't make - Russia wins. Much of it is made using Chinese tools - China also wins, because China right now need toolmakers, not just product makers.
