> Is there a public announcement/commitment saying that Apple does not share any data with China?
They have to share data:

> And even though Chinese iPhones will retain the security features that can make it all but impossible for anyone, even Apple, to get access to the phone itself, that will not apply to the iCloud accounts. Any information in the iCloud account could be accessible to Chinese authorities who can present Apple with a legal order.
> Apple said it will only respond to valid legal requests in China, but China’s domestic legal process is very different than that in the U.S., lacking anything quite like an American “warrant” reviewed by an independent court, Chinese legal experts said. Court approval isn’t required under Chinese law and police can issue and execute warrants.
Previous to this, the data was stored on American servers and subject to American legal safeguards.
