Permanently marking them as 'FAKE' in big letters on every chip before selling will probably be fine. Or buffering off all lettering, and setting a customer limit.
However the act of marking them would probably cost as much as the'll make from selling them. So it isn't worth it.
Sooner or later the honest sellers in China will get fed up with it, and force the Chinese government to act. Otherwise the honest sellers just can't make money, so there is a strong financial incentive to fix the problem. Its just a question of when.
