I have direct experience dealing with China. They are the counterfeit capital of the world. In fact, their own government encourages stealing technology and counterfeiting. A company I once dealt with, had spend millions on fighting a counterfeit computer chip that China had copied and started imported under a different name brand. The USA law says that once we win in the court, they can't import under that name again... so what do they do? They change the name and import under a different name. So, back to court to spend another million.... and it becomes and endless cycle of fighting the battle, but between each battle, they still make money on the imports that they have already sold.
That's why when I deal with people these days, I always tell them to be very carefull of there stuff. They WILL copy it. If it makes them just 10 cents per item sold, they'll sell millions and profit from it. Counterfeiting is in that culture. It's in that government.
