I found this article interesting.

This quote especially caught my eye:

 "With an expanding economy and a car fleet mushrooming with its middle
class, China has been searching far and wide for oil reserves. In
recent years China has formed alliances and joint ventures in
Venezuela, Russia and Brazil to produce oil, and Chinese companies are
competing to obtain large-scale contracts for exploration and
development of fields in Nigeria and elsewhere in Africa."

I wonder what is thought of the Chinese locally?  I'm reminded of various American oil companies who maintain staff in the Gulf, especially Saudi Arabia, and they keep pretty much to their own community hardly venturing into the country proper. 

I also wonder what this means for Chinese American relations?
