Modern slavery is a major concern, particularly within the sex industry...but I feel we must be careful how we tread...eastern europe and west africa are principal points of departure for slaves, but it should be pointed out "arab" states are not considered principal (or even minor players) in this trade.
Europe, Russia and other African states are the key players. So, far from millions of blonde, white european women turning up in some Sultans harem....its young Black African and Balkan women that are being shipped around the world. At least 23 million in total if you can believe it.

Having lived in Hong Kong for some time, one can say China is as active in the sex trade as any other nation. To suggest otherwise is to ignore history and real life.
