I disagree. It's the fact the Chinese can afford to live on about $90/month and the companies pay those wages.
If it were wages alone, then no one would manufacture cars in the United States or Britain. This is not the case at all; the reason being is productivity is key.
Second, even in the United States, capitalism went through the phase that China is going through now - it was just 100 years ago, in the era of sweatshops. The economic growth in China indicates that wage differentials will erode - this is already happening in India
In any event, you are not presenting an adequate argument for statism in the form of tarrifs, nor are you saying how corruption could be prevented by various companies bidding for the government's assistance. And often times they don't help.
