Let me repeat:

1)Lo value added industry:It helped urbanisation and provided jobs to rural migrants but being lo value added means it can't create much revenues. Figures of significant% of such exports are also exaggerated because it's total value of the merchandise, not the values (through assembling)added to imported components.

2)Core industry: Only the auto industry received large yank investment bcos of the huge internal chinese market, not for export to US; ever heard of yank investment in china electricity generation or HSR or steel making?

3)Hi tech: Under severe Yankie sanction/embargo.
