Chinese government officials have made sudden visits to Microsoft Corp offices in China, a spokeswoman for the company said on Monday, but declined to give any reason for the inspections.
Microsoft has been a focus of anti-U.S. technology sentiment in China since U.S. Prism, which used U.S. company's technology for cyber espionage.
In an e-mailed statement, the Microsoft spokeswoman said: "We aim to build products that deliver the features, security and reliability customers expect and we're happy to answer the government's questions," but declined to give any further information.
The world's largest software company has had a rocky time in China, including a call by state media for "severe punishment" against American tech firms for helping the U.S government to steal secrets and monitor China.
OneDrive cloud storage service was being disrupted in China.
In May, central government offices were Windows 8.
Nevertheless, the company has pushed forward with plans to release its Xbox One gaming console in China in September, forming distribution ties with wireless carrier China Telecom Corp and e-commerce company JD.com Inc.
