China has completely shut down iBooks Store and iTunes Movies in the country, just six months after they became available there.

Apple originally had government approval to expand there, but the government’s State Administration of Press, Publication, Radio, Film and Television reversed course and demanded that they be banned, according to a New York Times report.

An Apple spokeswoman said according to the Times: “We hope to make books and movies available again to our customers in China as soon as possible.”

Apple has been able to get its products approved in China with a lot more success than most other tech companies, but this is a major defeat for them. Apple is trying to keep sales flowing by expanding into a huge international market like China, meaning this move could be a big hit on Apple’s sales. China is the second-largest market for the tech giant after the United States.

China is cracking down on American tech companies, perhaps spurred at least in part by the leaks of former National Security Agency contractor Edward Snowden in 2013, which showed that the U.S. government was using technology made by American companies to spy on everyone, including its own citizens.

Apple announced in February it had expanded Apple Pay into China, a major victory for the company.

“You can now support Apple Pay for your customers in China, providing an easy, secure, and private way for them to pay using their China UnionPay credit and debit cards,” Apple said in a statement. “Apple Pay lets users buy physical goods and services within your app without having to enter payment or contact information.”
