Maybe I can just add that the Pacific Alliance, as we understand it, is a new initiative among four countries that already have free trade agreements with each other. Indeed, one of the requirements of joining the Pacific Alliance is that the new members have to already have free trade agreements with all of the existing members.
The TPP is different in the sense that not all of these countries already have free trade agreements with one another. It's a much bigger grouping. It's already trans-Pacific. It's quite a different animal. Its purpose is to create basically a free trade zone across the Pacific with 21st century rules, etc., to support that trade.
So these have two different objectives, I would say, and potentially complementary.
