According to link below, some people think that Brazil is a good place to start investments (in a poll with 26 votes titled "And where do you put your money in the future?", 50% people choose Brazil). Joe Wyka user thinks Brazil is well positoned on board...

A quote from there:
[...]This was a weird game. I don't quite remember how things started out,
but Adam was trying for a US/Brazil combo, and the rest of us were
kinda spread around. For the first half of the game things went pretty
slowly, but we all had a decent cash flow - countries weren't taxing
for very much, but just enough that we were able to reinvest, and the
countries were fairly balanced. India was looking good but fragile for
a while, everyone was in Brazil, which was doing well (as usual) [...]
Eventually though after a series
of close Investor actions everyone except me had a big wad of cash,
most of which ended up in Brazil. India and Brazil started moving up
the power track fairly quickly (due to cross investments by Charles
and Garrett, their owners), while China harassed the US (which was
unable to slow Brazil) and Europe and Russia fought. Charles and
Garrett had huge investments, Charles in India/Brazil, and Garrett in
Russia/India/Brazil. I had a decent spread across all countries except
China, and Adam was mostly in Brazil/US/Europe. The game ended
semi-unexpectedly when Brazil jumped to tax to just make it to 25.
Final scores:
Brazil 5x India 4x US 2x China 2x Russia 2x Europe 2x
Garrett 205 Charles 186 Deniz 144 Adam 129
If Charles hadn't ended it right then, Europe and Russia would have
each jumped up to 4x, which would have put me in a better position but
would also have put Garrett even further into the lead. I was hoping
all the countries would level out at about 4x, given how slowly it was
going (I had about ~7 interest in non-Chinese countries), but those
who were big in India and Brazil only (Charles and Garrett) won out.
