South Korean Newspaper The Chosun Ilbo has a report on the thriving traffic of humans on the border between China and North Korea.

From the english version of the Chosun Ilbo:

A 26-year-old North Korean woman, Mun Yun-hee crossed the Duman or Tumen River into China in the dawn of Oct. 22 last year, which at that point was some 40 m wide, guided by a human trafficker. She was being sold to a single middle-aged Chinese farmer into a kind of indentured servitude-cum-companionship. Both of them wore only panties, having stored their trousers and shoes in bags, because if you are found wearing wet clothes across the river deep at night, it is a dead giveaway that you are a North Korean refugee.

An estimated 50,000 to 100,000 North Koreans are living in China.

Human Trafficking is a $32 billion business worldwide.
