That's what the Washington Post reported. Laura Ling and Euna Lee, the two jailed American journalists, were working on a story about the trafficking of North Korean women in the border area of China and North Korea when they were detained. As you've no doubt heard, the two journalists have been sentenced to 12 years in a N. Korean labor camp, while people and governments around the world try their best to secure their release.
The trafficking of North Korean women in China is a longstanding issue that human rights groups have continually called the world's attention to. Thousands of North Koreans have fled famine, poverty, and political repression and crossed into the border. However, younger or middle-aged North Korean women who do so have run smack into China's own demographic problem: the woman shortage (30 million single men by 2020). The Post article provides a good overview of the situation. Chinese men that are older or can't find a wife through more normal means buy north Korean wives. Though it would probably be hard to find reliable information on buying a north Korean wife, there are a few douchey posts about this where the price of a wife is listed as around 10,000RMB.
The Chinese media has some articles on this subject as well, though nothing very comprehensive. There are various organizations of people that smuggle the North Korean women over the border. In one case, of the men that were caught, one was given as much as a twenty year sentence, while others received as little as two or three years. Little is said in these articles about the Chinese government policy of denying these women political refugee status, much less the ethics of the repatriation policy.
You can see some moving photos of North Korean refugees here.



Just out of courtesy, you could mention that this photo is from Katherina Hesse.
Also she says on Flickr: "This image may not be reproduced without expressed written permission from Katharina Hesse. Any blogging, unauthorised use and/or distribution of this image is prohibited." so I hope you have her permission to reproduce it.

Than you for notifying us, Lucas. We have removed the image.
Well, now you are on the safe legally speaking. But you could just ask her and if you offer to put her name and a link to her website http://www.katharinahesse.com/, she might say yes. It is just this attitude of doing things behind people's back until caught that I don't understand. Being a photographer myself, I suffer from it. Oh well I must be the last of the Mohicans, right?

Lucas,
We noticed the problem yesterday immediately after the post went live. It was supposed to be removed immediately, but regrettably that didn't happen. We apologize for that. It is our policy not to use copyrighted materials without permission. This is something we take seriously. Again, sorry we didn't catch this one in time.
