It's a thin facade.
Russia is dealing with intrusion into its territory from the South. Siberia is vastly mineral wealthy, as are many of the former soviet nations.
China has fewer pure ores than many other nations and relies more on cheap processing than on its own mineral wealth. The problem is that if other nations begin waking up to the fact China is trying to destroy all base manufacturing in its rivals - they will stop exporting labor (and realize their citizens are going absolutely insane with imposter syndrome and other paychological maladies from not doing anything productive with themselves).
…. Assuming the people in charge of said rival nations actually care about their populations and believe China will have any respect for them once done using them.
