Not likely, Brazilian manufacturing has been in the doldrums for a long time and shows little promise of changing, their economy is driven very much by mining and farming, soon oil extraction will be in full swing and so manufacturing won't get much of a look in. That sector suffers when those others soak up all the investment capital and inflate the currency, not to mention when the government runs a high deficit which also soaks up capital (which is increasingly the case there). And on top of all that, the Brazilian government interferes too much, which prevents investment. And they impose punitive import tariffs, which guarantees they would end up in a brutal trade war should they chase that sort of business. Bangladesh, Vietnam and their ilk are the countries where cheap assembly manufacture is going to move to. But there's still plenty of dirt poor regions in China for them go to as well.
Meanwhile the Chinese are investing increasingly in plant to replace workers (which is why Germany has done so well lately). Foxconn and others will be shedding millions of cruddy jobs over the next decade, and it's far from obvious what those people are going to do for a living - so far China has taken steps to prevent services and retail flourishing, but those are the areas that should soak up excess workers. So the next time you encounter some dufus wittering on about how China will inevitably be the global economic superpower, and countries like ours are destined to be subservient to them, try to help them learn that things are more complicated than that.
