Yes. That's a very good question, a hard question.
It's a hard question because I worked many years ago at the Andean Community. I was based in Lima and I spent a few years there. At the time the Andean Community was an example of integration. We managed to multiply trade with our partners in a relatively short period of time. Once we opened the barriers and we started to harmonize rules, trade with our partners increased dramatically. However, that's no longer the case. There are unfortunately a number of barriers that are difficult with some of the trade in the Andean Community. That is a regional integration bloc that is going through a relatively difficult time in some respects. As you know by the history, some countries have come in and others have left.
Mercosur is an important bloc. It has the largest economy in South America. I don't want to comment on a bloc that Colombia doesn't belong to. I certainly think that the initiatives of many integration blocs are similar. The objectives of many integration blocs are the liberalization of goods, services, capital, and people. I think it's very important—as we have in the WTO, when you look into this—that we have strong dispute settlement mechanisms. Where you're missing them, it is not easy for investors and the business community. They're all different, but they are very similar in many aspects.
