There are different types of dispute settlement in NAFTA. You mentioned chapter 19, which relates to trade remedies, anti-dumping, and countervailing duties. There's also the state-to-state dispute settlement process under chapter 20, and there's an investor state dispute settlement process under chapter 11.
With respect to chapter 19, the proposal we have put on the table is not simply to preserve chapter 19 as it is; it's to modify chapter 19 to improve it, to make it more efficient, to make it more effective, to provide some comfort with respect to some of the U.S. concerns and ensure that it remains an effective instrument going forward.
We have outlined in our proposal specific elements to improve chapter 19. We think it is fundamental, given the record of the past. We have taken chapter 19 cases on 20 occasions. The U.S. has been required to go back and change its practices on 13 of those occasions. It has been an effective instrument for us, and I think it's a basic kind of element that we need in the agreement to ensure fairness.
