Some friends of mine have one daughter from China. They tell us that because of his diabetes and her obesity they will probably have to look at Vietnam for another adoption.
Supply and demand...even affects the communists, eh?
LOL, they are fairly adept at our economics, just not in favor of applying it on a large scale for their own citizens. China also often limits adoptive parents to adopting one child from them, and, I've heard, having no more than one child already in the home, with few exceptions. I'm not sure why, except maybe to mirror it's own one child policy.
