China’s antitrust watchdog is laying the groundwork for a potential probe into Apple’s policies and the fees it charges app developers, part of a broader push by Beijing that risks becoming another flashpoint in the country’s trade war with the US.

The State Administration for Market Regulation is examining Apple’s policies, which include taking a cut of as much as 30 percent on in-app spending and barring external payment services and stores, people familiar with the matter said. Agency officials have spoken with Apple executives and app developers since last year, said the people, who asked for anonymity to discuss sensitive moves.

The conversations stem from long-running disputes between Apple and developers such as Tencent and ByteDance over iOS store policies — a source of tension between the US company and regulators worldwide. While Beijing has since 2024 targeted the practices of US tech firms from Nvidia to most recently Alphabet’s Google, regulators may not formally move against Apple if the current conversations go well.

Chinese regulators believe that Apple may be charging local developers unreasonably high fees, the people said. They think the barring of third-party app stores and payment methods also hinders competition and hurts local consumers, the people said. If Apple resists making changes, the government may launch a formal investigation, the people added.
