any app in the apple store
that does not also register
their app with the chinese govt
will not be sold in mainland china
this is a mandate
by the chinese govt
so in effect
there are probably thousands
of apps that are banned
from purchase in mainland china
i don't know what conditions
the chinese govt might
enforce in that registration
process to limit apps for sale
apple provides a link
to the site for registration
i clicked on it out of curiosity
it was entirely in chinese
