Maybe she's also trying to show how, in the face of other countries turning their backs on poor, misunderstood and down-trodden Argentina, there are countries that are also ex-colonies of someone (Portugal in this case) that the true leaders of the anti-colonialism and worker's paradise like Argentina will show them how to shake off their yokes.
I've been to Angola, though about 11 years ago. What a s**t hole it was then. We drove around with guards armed with Uzis, in a Range Rover, the vehicle which was needed to avoid and/or navigate the craters and ruins made by bombs in the middle of Luanda. Talk about poor people. Angola makes Paraguay look like a rich country.
Maybe it's changed somewhat since then, but when I was there, it was called the most expensive city in the world for foreigners, and I believe it still is. And the reason they call it that is because the country produces very little of its own things, and any item that is not basic subsistence type items must be imported. Of course, the extraordinarily corrupt government impacts imports as well by their high import duties...
Maybe Cristina, et al, are thinking that they can actually export to a country such as this and make some money. Obviously not oil (that would be a double whammy), but seeing as how they are so clueless about what they've done here, blocking imports in an attempt to keep dollars in the country and at the same time thinking they can magically up production to cover the lack of incoming goods, they think also they can produce enough to offset some of their trade imbalances here by exporting to another country, who is much more truly a victim of outside influences than Argentina ever was or is currently.
Truly, I bet she's just grandstanding to show the people here that Argentina is a world-wide going concern, but with one of the few countries in the world that would actually accept overtures because they are so poor and down-trodden.
