On trade specifically, it would have to be with all Mercosur countries. Because they're a customs union, they negotiate only as a block on free trade agreements. There are some aspects that they can negotiate bilaterally. We have a foreign investment protection and promotion agreement with Argentina and Uruguay. We've had some initial exploratory discussions on investment with Paraguay.
So for investment, for example, it's possible that we could do individual agreements. But for a comprehensive free trade agreement, it would have to be with the group as a whole, which poses some additional challenges because, as a group, they aren't really that clear yet on where they stand in terms of services, in terms of government procurement, and in terms of investment. They're currently having interim Mercosur negotiations on those questions, and so have a difficult time working with third countries to determine how they would treat those in a free trade agreement outside the block.
