The point is that even without China or anyone, just by itself Russia is already a status-quo superpower that can confront US. Debt-driven consumption GDP in many services (e.g. movies, casinos, spa, beauty salons, ...), even in some light manufacturing (e.g. furniture, fashion, jewelry ...) with shallow supply chain, play insignificant role in war time confrontation. Russia has good human capital, powerful base of heavy industries, vast reserves of strategic materials, battle-hardened military, geopolitical influence, these make Russia the only other superpower in the world.
But yes bro, China is a value-adding strategic partner for Russia in her global confrontation with US, no doubt on that.
Agree to that bro.
Other than Russia, the only two nations that can be superpower on par with US/Russia are Japan, if they decides to re-militarize & re-build "Greater East Asia Co-prosperity Sphere" ("大东亚共荣圈"), and Germany, if they are successful with changing EU into "Forth Reich" ("Viertes Reich").
China's mission is to revive cultural & economic prosperity of the Middle Kingdom as well as partnering nations, with a modest peace enforcement branch just suffice to defend national interests, home & abroad.
