Before I pass this to Mr. MacKay for a more detailed answer, the Pacific Alliance is about two things. It's about reaching out to the Pacific region, but it's also about deeper integration amongst the members to enhance trade and cooperation amongst them—which isn't focused solely on the Pacific region.
So in answer to your question, no, I don't see it as a duplication at all. I see them as complementary initiatives.
I'll turn the floor over to Mr. MacKay to answer in more detail.
