> the one child policy has backed them into a corner
A policy that ended a decade ago, and was only ever marginally successful (even at the height of the restrictions their birth rate was nearer 1.4 than 1.0)
The one child policy was only for cities anyway. Agricultural areas were permitted, even encouraged, to have more children. There were other exceptions, like twins (obviously), if the first baby was disabled, etc. Later on, couples were allowed two children if both parents came from single-child families.
