Basically they do the same (mistakes?) everybody else is doing, the USA, Europe, Japan ect.
Their only advantage is, that once they decide to do something its getting done. Without having to negociate with political opposition or bankers or other interest groups.
That can be very advantagous if the decision is a good one, but also very destructive if the decision is wrong.
I tend to believe that Chinese know what they are doing when it comes to making business. They have always been really good at that.
