Afsaneh, if you could indulge me on something...how much manufacturing and non-pertoleum activity goes on in Iran? It seems the few petro states that have succeeded long term have done so by diversifying their commerce. I understand your country is under trade sanctions with much of the West, but eventually that will change (Persian culture is not going anywhere) as things always do.
Oil is often as much a curse as it is a blessing, and I don't really know much about Iran, so I am curious about what other interests the country puts its investments.
