Lula’s always been pretty good with calling out other people’s bullshit around Latin America, it isn’t particularly surprising that he’d do that (and the same applies to Biden). Shame that he doesn’t have the courage to do the same with Russia though, even if that’s more because Russia has held Brazil’s agricultural market by the balls for a while now.
Given the historical record on attempts at Mercosur-EU trade deals, this is likely to fail yet again, since the EU’s agricultural voting bloc (mostly in France and Italy) doesn’t really want the market to be populated by cheaper products from abroad (at least not any more than it already is). But at this point, given the several ongoing food crises that Russia’s invasion of Ukraine caused, the chances for a successful agreement are about as high as they can go, so they might as well go for it.
