Apple shares fell on Wednesday after Bloomberg reported that Chinese regulators are considering whether to open a formal probe into the iPhone giant’s App Store fees and policies.

Shares of Apple were down 2.66% at 09:34 a.m. London time in premarket trading.

The State Administration for Market Regulation (SAMR) is looking into policies that include Apple taking a cut of as much as 30% on in-app spending, as well as blocking third-party payment services and app stores, Bloomberg reported Wednesday, citing people familiar with the matter.

China’s market regulator has not decided whether to formally open an investigation into Apple, according to the report.

Apple and China’s Ministry of Commerce was not immediately available for comment when contacted by CNBC.

The news comes as trade tensions between the U.S. and China ramp up under the administration of President Donald Trump, one month into his second term.

Apple has maintained that its strict App Store policies are designed to protect users and improve the experience across its products.

China this week also opened a probe into Google over alleged antitrust violations, although the market regulator did not supply details over the focus of the investigation.

The Financial Times reported on Tuesday that the SAMR is also considering a probe into U.S. chipmaker Intel.

Apple’s App Store has come under scrutiny from regulators globally. It was forced to open up its App Store in Europe, under the sweeping Digital Markets Act in the EU. This means that it now allows non-Apple companies to offer app stores in Europe, and app developers can also use third-party payment systems.

If the China probe goes ahead, it would cause further headache for Apple in one of its biggest markets. The Cupertino giant is already facing stiff competition from local players like Huawei that are eating away at its smartphone market share. Apple sales in Greater China declined 11% year-on-year in the December quarter.

Japan’s Toyota Motor on Wednesday reported a second consecutive fall in quarterly profit, while announcing that it will set up a new company in China to make electric vehicles as it plays catch up with automakers focused on EVs. 

Here are Toyota’s results compared with estimates from analysts, compiled by LSEG.

• Revenue: 12.39 trillion yen vs. 12.1 trillion yen
• Operating profit: 1.22 trillion yen vs. 1.39 trillion yen

The world’s largest automaker by sales volume saw a nearly 28% year-on-year drop in operating profit during the quarter ended December.

The results mark Toyota’s second consecutive year over year decline in operating profit after the company saw profit fall 20% year over year in the previous quarter.

Net income attributable to the company, however, jumped to 2.19 trillion yen from 1.36 trillion yen a year ago.

The automaker’s consolidated vehicle sales for its financial third-quarter dropped to 2.44 million from 2.55 million units a year ago.

Still, Toyota maintained its full-year dividend forecast at 90 yen, compared with a dividend payout of 75 yen a year earlier.

Toyota said it will establish a wholly-owned company for the development and production of Lexus BEVs and batteries in Shanghai, China. The new company is expected to start production in 2027.

Toyota shares rose over 1% in Tokyo on Wednesday.

The company saw its operating profit drop in the key North America region by 113.7 billion yen in the December quarter, year on year, while it declined by over 46 billion yen in Asia. 

Toyota has been slower than competitors at embracing fully battery-powered electric vehicles, and instead has focused on hybrids, according to local reports.

The U.S. Postal Service said Tuesday it’s temporarily suspending all inbound packages from China and Hong Kong Posts.

The change is effective immediately and will remain “until further notice,” according to an alert posted to the agency’s website. Letters and large envelopes, referred to as “flats,” sent from China and Hong Kong won’t be impacted, the USPS said.

The announcement comes after President Donald Trump on Saturday signed executive orders imposing tariffs on China, Mexico and Canada. Trump on Monday agreed to hold off on imposing 25% tariffs on Canada and Mexico for 30 days, but the 10% tax on goods from China remains.

A provision in the orders eliminates a popular trade loophole, known as “de minimis,” which allows exporters to ship packages worth less than $800 into the U.S. duty free.

Chinese e-commerce firms, including Shein and PDD Holdings‘ Temu, have relied on the de minimis loophole as a way to bypass tariffs, and keep prices low.
