When I responded to your earlier question, I said that I felt petty corruption had reduced significantly in Russia. I cited the example of customs, where I think there's been a lot of cleaning up.
I think that where you get a concentration of political and economic power in any country, you tend to get a concentration of the potential for corruption on a fairly grand scale. I would say that may be what Transparency International is indicating.
I think nowadays there is less impediment, at an operating business scale, than there used to be. But I suspect that if you wanted to win a contract to build a huge oil refinery, there might well be people coming to you and saying, “I can help you with that.”
