Actually, China goes way beyond that. Where the U.S tries to nudge things one way or the other indirectly (by changing interest rates and the like), China has total control over their economic & monetary system (including the banks). And they exert that control almost daily. It's one of the reasons why the Chinese Yuan will replace the dollar as the world's reserve currency.

I think the US and the UK interfere plenty. At least China isn't pretending they are against central control whilst pumping out "free market" rhetoric.

The US let Lehman fail which was about all they could stomach.

China has vaporized trillions already trying to bail out their banks, which are extremely over-leveraged on debt. China's entire banking system is under high duress right now due to the 'shadow banking' debt mess.
