I think there's no question that they're stronger as part of a three-way relationship. First of all, with NAFTA, Mexico becoming involved in the agreement that we'd previously had with the U.S. certainly was very important to the development of the Mexican economy. The Mexican economy has grown. Of the three counterparts, the U.S. is clearly number one; there's no doubt about that. But I had frequent opportunities for discussions with my counterpart, the Mexican ambassador to the United States, while I was in Washington. I think we were able to discuss common problems to the benefit of all three countries, no question.
Let me make a brief comment on the visa question you raised in your earlier comments. I think it's important to remember why this came in, and you put your finger on that. It happened when I was in Washington. We didn't do that in a way to disadvantage Mexico or anything like that. It was to address the problem that you've just described. Unfortunately, it's harder to change things once they're established rather than in the earlier decision to bring it in.
I guess the only point I'd make is that at that time, there was significant net immigration into the United States and Canada. Now that this has settled down—in fact, probably net immigration is at zero—people are moving back, from the United States in particular, to Mexico. In fact, I read somewhere that it's causing problems with some of the cities in Mexico on the northern border.
I think now is an opportunity to remove something without having a significant reaction comparable to what we had when we brought it in in the first place.
