A Chinese law firm has filed a complaint against Apple on behalf of 28 local developers alleging the firm breached antitrust regulations.
The complaint was lodged by Dare & Sure Law Firm in Beijing, who told Reuters on Thursday that they had invited the developers to join in on the case last April, though the firm declined to provide details on the parties involved.
Apple has been facing multiple challenges in China. In addition, the developers are accusing Apple of charging excessive fees for in-app purchases.
Apple started a worldwide crackdown on what it sees as illegitimate apps earlier this year, and removed 58,000 Chinese apps in one swoop in June, according to tech research firm ASO 100.
Inconsistencies and lack of transparency in app approvals is a complaint that has been made by developers in Apple's home country too. In the USA, numerous developers have complained about the company's policies in the past.
It has also announced plans to open a data center operated by a government-backed company to store user data locally, the report said.
The NDRC and SAIC did not immediately respond to requests for comment. Aside from declining sales, the company has to contend with the government's efforts to tighten control over the internet.
China made more money for Apple's App Store a year ago than any other country, according to research firm IDC. "Apple will definitely deny that, such as claiming the relevant market should at least refer to all smartphone application stores, in which it would not have a dominant market position".
