The next world giant
Money - investment - tends to go where the cost is low as it make potential profit higher. And Brazil this year will be reducing a major cost. Effective the end of this year, Brazil will not be using petroleum to fuel the cars and truck on the road. It'll be using ethanol produced from sugar cane. It's been working toward this for a long time and is literally facing the end.
A few interesting notes. First, the process is break-even against petroleum based fuel when the price of oil is about $45 per barrel. Second, ethanol isn't quite as energy efficient as petroleum - slightly fewer miles per gallon available. On the other hand ethanol burns with a lot less complex waste - less pollution per period of operation. And for those wanting to jump, corn ethanol is more expensive to produce than sugar-cane ethanol. Still, in the United States approximately half the crude oil we bring in goes to producing finished motor gasoline (per the IEA).
Back to the original point. I fully expect - based on what the experts in the industry are saying - that oil is going to continue to get more and more expensive (call it peak oil or something else). Brazil's gotten off that risk line, and the higher it goes the more tempting its local costs are going to be for outside investors. Them that have, get, and Brazil's got.
