Chinese officials this week issued a stern warning to Microsoft: don't interfere with our antitrust investigation.

China's State Administration for Industry and Commerce (SAIC) recently questioned Microsoft's Deputy General Counsel, Mary Snapp. But in a later statement, SAIC warned Microsoft that it "should strictly abide by Chinese laws and may not interfere [or] in any way hinder investigation of the case, to ensure an objective and impartial investigation."

Neither the SAIC nor Microsoft immediately responded to a request for comment.

Local officials recently showed up unannounced at Redmond's Beijing, Shanghai, Guangzhou, and Chengdu offices. The agency, according to The Wall Street Journal, accused Microsoft of not disclosing certain information about security features and its software.

A company spokeswoman last week told PCMag that "we aim to build products that deliver the features, security and reliability customers expect, and we will address any concerns the government may have."

The probe began about two months after China reportedly banned the latest Windows operating system on government computers: All desktops, laptops, and tablets used by central state agencies must run on an OS other than Windows 8.

Earlier this year, Microsoft denied censoring Chinese-language Bing results in the U.S., calling any restrictions a glitch.

Despite China's suspicions toward Microsoft, the company's Xbox One gaming console is set to arrive in the country Sept. 23, with a 3,699 yuan ($599) price tag and a handful of games, movies, TV, and sports viewing options.
