Dear Steve,

It's a impossible task for Apple and the likes to maintain a 
store of device decryption keys.Where should these keys be stored? 
China will not trust the US to hand over the keys. So China
will demand Apple to store the keys within its border. 
According to the language of "manufactured… and sold", then 
this means China can demand Apple to store all the keys 
inside China and be readily available to the government 
without any warrant as netizens of China have no privacy rights.
