A small oil rich country in southwest Asia?
It's not really a small country, small country would be Singapore or Kuwait. And regarding it's oil reserves, im not really sure because there is no statical data on the net.. Also, the geographical location of Uzbekistan is called Central Asia not South-west Asia, though IT IS LOCATED in the south west part of Asia :))
The distribution of oil did affect Southwest Asia because the people with oil are rich but the people that don't have oil don't have that much money. There was a relationship between the two because of the money and stuff, so if the people who don't have oil don't have that much money then they won't have money to buy things for Southwest Asia
