If all Chinese food products and ingredients are embargoed, I think that might get their attention. And if that becomes the reliable consequence of this sort of thing, that may result in some changes
Heck, don't wait for the government to "protect" you. Why not just BOYCOTT Chinese goods wherever possible? And then, if you feel a need, write the appropriate letters stating exactly WHY you're not gonna buy Chinese goods anymore...
I will not buy Chinese-origin food, but I have no way of knowing what ingredients in the foods I buy might be from China
