SE Asia is a continued hotspot for both a source and a destination for human trafficking and sexual slavery. According to Free the Slaves, SE Asia and the Pacific has by far the highest number of victims of slavery and trafficking, with estimated numbers around 24 million (By comparison, the United States has an estimated 145,000 victims).
Every estimate is that there are more than a million children who are effectively enslaved. The UN said more than a million in Asia alone. The Lancet, the British medical journal, said that 10 million children were in brothels around the world. And you know for many of them it is absolutely like 19th century slavery, except that they are all dead of AIDS by their late twenties. - Nicholas Kristof
