I'm not across the current ownership breakdowns and state partnerships in South America (once upon a time I'd have quoted such things down to share percentages and layered subsidiary's) - the comment intrigued me as it's plausible there is some resource advantage to be gained by siding with one side of politics in Brazil, it's certainly the case that many large scale international dramas have at their core something that tracks back to resources and potential profits.

Controlling percentages can change, as can state restrictions on a number of conditions.

As I said it's not something I've dug into the details of.
