China's antitrust regulator is reportedly preparing to investigate Apple's App Store policies and fees, including its 30% commission on in-app purchases and restrictions on external payment services. The move follows recent measures targeting US businesses, including Google and fashion brand Calvin Klein, just as new US tariffs on Chinese goods emerged. Apple's shares fell 2.6% in premarket trading following the news.

The investigation, led by the State Administration for Market Regulation, comes after ongoing discussions between Chinese regulators, Apple executives, and app developers over the past year. While neither Apple nor the Chinese antitrust regulator has commented on the matter, the move is seen as part of broader scrutiny of US companies operating in China.

In a separate development, Google was also accused of violating China's anti-monopoly laws, with experts speculating the probe could be linked to Google's Android operating system and its influence over Chinese mobile manufacturers. Additionally, China's Commerce Ministry added PVH Corp, the owner of brands like Calvin Klein, to its "unreliable entity" list.
