More than three decades after it began, China's one-child population control policy has some unintended consequences. Because of a traditional preference for boys, thousands of couples abort female fetuses, and the Chinese government says that last year, 119 boys were born for every 100 girls. The shortage of young women is pushing some families turn to human traffickers to find wives for their sons. The traffickers often go to neighboring Burma, Mongolia, Vietnam, Laos and North Korea to buy or kidnap women. Henry Morton recently visited Nabang, just inside China's border with Burma and has this story.
