That distinction is made because the trade remedy law is not designed for this purpose. You can use your countervailing duty laws—which are all organically derived from the WTO—but they have to be in reference to imports from the United States of subsidized product. You don't have enough of that to be worried about. What you're worried about is that you can't penetrate the American market and compete there, and it's because of the subsidies. So the countervailing duty law doesn't help you. I don't think chapter 11 is much help either, certainly not as designed.
I'm not calling for the abolition of NAFTA.
