Well, sort of. I can't access the Wall Street Journal article World Magazine links to, so I'm not as sure of the details as I'd like to be.
I guess they realized how critical their woman shortage has gotten. I'm not sure they realized that their policy turns out to be sexist given the negative impact on women that it has (even though there was no sexist intent). They absolutely don't admit anything bad about the near-forced abortion policy. Still, their decision to allow parents to have another child if they have a girl is a step in the right direction.
