Earlier the Chinese Ministry of Industry and Information Technology (MIIT) said that it has granted a network access license to iPhone 6.
The license came after weeks of delay for the release of the phone which had resulted in largescale smuggling from Hong Kong and US even though Iphone is manufactured in China.
Chinese police have seized large stocks of smuggled iPhones in airports recently.
The MIIT said in a statement that it made the decision to issue the license after getting reassurance from Apple that three background service programmes, which reportedly had risks of personal privacy leaks, are only diagnostic tools that won't be used maliciously.
Apple also said it will improve security and privacy protection for its clients.
The company said it has never and will never set up so-called "back doors" in any of its products or services in cooperation with any government organ of any country.
The MIIT said it pays great attention to protecting mobile phone users' personal information and will strengthen security management of mobile phones, the statement said.
