We don't complain about the washington-based World Bank. Of course World Bank has to work on the interest of the United States. But China has it own interest, if the interests of the US and China can overlap, that is excellent, if the interests are on different sphere, then China should take own steps.

a country is like an organic life. Self-regulating is very important for its well-being in terms of biology and control theory. Say, your body is exposed to heat, it self-regulate using sweating system.  Inteference from outside force can lower the chance of its survival. 

If dear World bank is so smart, why don't give some good medicine to the US, or at least give the US some warning before its economy falls? Why World Bank should send fear around the China if they cannot help self even.
