I've never been sold, as Eduardo said, that the concept of MERCOSUR is ever going to progress beyond some sort of reduction of internal trade barriers between them, internal tariffs. I do think it was born more as a political concept, really, than an economic concept.
There are plenty of commentators now who would say that MERCOSUR, to a certain extent, is in tatters. Everybody is fighting with everybody. We all know about the fight between Argentina and Uruguay right now on a paper mill; and Brazil and Argentina always have their issues. So I don't see that as some huge powerful bloc.
The reality of it is that if Brazil and the U.S. and Europe can work out their agricultural issues, Brazil is on board with other issues. So I just don't see that as a huge stumbling block.
