This is an odd distinction to draw. What do you mean by done in this case?
The CPC much more closely controls their internal markets so the fact that companies are not doing the whole "circular investment" game is a direct result of policy decisions made by the CPC rather than companies in China just sort of "deciding" not to hop on the band wagon.
The CPC didn't send a task force to fight the money demons but they did implement policy that led to this state of affairs, which is what they're supposed to do.
