Apple App store peddles stolen Chinese books?

Anyone can submit apps for Apple’s approval in order to be available for sell at Apple App store. Now, I am curious what legal responsibility Apple has in ensuring the sellers actually have the proper rights? In particular, I wonder how does Apple ensure proper copyrights for foreign languages books?
I wonder if Apple simply asks all apps sellers to sign legal documents claiming they have proper legal and copyrights to sell whatever they try to sell and indemnify Apple in the process?



Ni Kuang (倪匡) and Yi Shu (亦舒) are two famous Chinese authors in Hong Kong and many of their books are still in print and available for sell in bookstores. So it came to me as a big shock and surprise to see a collection of 712 (yes, seven hundred and twelve) of Ni’s books (倪匡作品全集(简繁体712部)) and a 200+ collection of Yi’s books (亦舒小说集200+部（簡繁體）) available for sell for only US$2.99 and $1.99 respectively!!!

Wow, $2.99 for 712 books and $1.99 for 200+ books, what a deal if it is legit?! From what I can gather, Yi’s books collection has been available for purchase at least since a Oct 30, 2010 update. And Ni’s books collection has been available for purchase since Dec 30, 2010.

Both ebook collections are being sold by a seller name “Jingang Chen”. I don’t know if this “Jingang Chen” person has the proper legal rights to sell the books collections or not, I do hope Ni’s and Yi’s authorized publishers can check and confirm if these two book apps are indeed legit.
Hate to see anyone selling stolen copyrighted materials so internationally and so easily.
