A lot of money was made very fast during the privatization of the Soviet Union. Not really surprising at all
beijing has much more billionaires than 100 if including corrupted communist officers and underground wealthy people
Really wealthy people stay as far away from the media light as they can. Between government shakedowns and kidnappings, the world is a dangerous place.
If those Chinese billionaires are underground, then you would not even know them. How can anyone compile a list including them??
