China is preparing for a potential probe into how Apple deals with developers, including taking a 30% cut on in-app spending, according to a report.

China's stocks and currency came under pressure as markets returning from a week-long break were greeted by a new trade dispute with the United States and ructions in the global artificial intelligence sector.

Apple stock fell Wednesday after Bloomberg reported that the Chinese government is exploring the launch of an antitrust probe into the company’s policies.
