China is considering opening an antitrust investigation into Apples App Store commissions, mirroring those already carried out in the US, EU, and elsewhere.However, its likely that the Chinese government is simply raising the possibility as a form of leverage in the latest trade war instigated by the Trump administration Investigations and lawsuits elsewhereApple has already faced antitrust investigations and action around the world, through a mix of legislators and lawsuits from customers and developers. The core argument has been that because Apple had monopolistic control over the sale of iPhone apps, it was free to set its own commission rates and terms, and developers had no choice but to agree.The most dramatic change happened in the EU, where the Digital Markets Act required Apple to allow iPhone and iPad apps to be sold throughthird-party app stores. Apple did its best to make this option as unattractive as possible for developers in what has been described asan act of malicious compliance, and its likely that it will be forced to change its terms.In the US, Apple suffered a smaller loss, when a case brought byEpic Gamesresulted in the company being told that it must allow developers to link to alternative ways of purchasing in-app content. The company again complied in a way that would protect its commissions, and the judge in this case has indicated that Apple islikely to be found in breachof her ruling.There have also been similar investigations and lawsuits in a number of other countries, including Australia, India, Korea, and Japan.China considering antitrust investigationThere have been mumblings before about possible antitrust investigations in China. A lawsuit was filed by an iPhone owner back in 2021, but that case was dismissed when the court ruled that Apples commissions were in line with those on Android app stores, and there was no evidence that consumers ended up paying higher charges.However, Bloomberg reports that the countrys antitrust regulator is considering opening an investigation.Chinas antitrust watchdog is laying the groundwork for a potential probe into Apple Inc.s policies and the fees it charges app developers, part of a broader push by Beijing that risks becoming another flashpoint in the countrys trade war with the US.The State Administration for Market Regulation is examining Apples policies, which include taking a cut of as much as 30% on in-app spending and barring external payment services and stores, people familiar with the matter said.Likely leverage in trade warWhile China has long murmured about the possibility of antitrust investigations into Apple and other US companies, the timing of this news is unlikely to be coincidental.While Trump hasnt yet acted on his threatened chip tariffs, he yesterday imposed a blanket 10% import duty on all goods arriving from China. The Chinese government responded by imposing tariffs on some US imports, and literally seconds later announced an antitrust investigation into Google. The announcement about Apple followed shortly afterwards.A similar thing happened when Trump instigated a trade war against China during his first term, with Apple a key target for retaliation.That being the case, its likely that China wants to initially hold out the threat of an investigation as leverage, and then if that doesnt achieve anything it will proceed at that stage using the threat of a finding against Apple as stakes in the trade war.Photo of Beijing skyline byzhang kaiyvonUnsplashAdd 9to5Mac to your Google News feed.
