The State Administration for Industry and Commerce said it opened a case in June after complaints Microsoft improperly failed to publish all documentation for its Windows operating system and Office software. It said investigators visited Microsoft’s China headquarters in Beijing and branches in Shanghai, Guangzhou and Chengdu in southwestern China this week.
“The administration believes the previous investigation cannot eliminate that Microsoft engaged in monopolistic behavior,” the agency said on its website. “The administration has launched an investigation of Microsoft’s monopolistic behavior.”
Microsoft did not immediately respond to a request for comment.
Foreign technology suppliers face growing pressure from Chinese regulators, who have launched anti-monopoly investigations and announced plans to examine products for security flaws.
China relies heavily on foreign software and communications technology. Communist leaders have expressed frustration about the high cost of foreign know-how and have invested billions of dollars to develop their own phone, encryption, software and other technology industries.
Chinese state media have stepped up criticism of foreign technology companies following disclosures by former National Security Agency contractor Edward Snowden about their possible cooperation with U.S. government surveillance.
In a separate case, state media said last week regulators have concluded Qualcomm Inc., a San Diego, California-based maker of chip sets for mobile phones, has a monopoly. The reports gave no indication what penalties or demands for changes in its business practices might be demanded.
Regulators said earlier they were investigating whether Qualcomm abused its dominant market position by charging excessive fees for technology. They announced a similar investigation at the same time of InterDigital Inc., in Wilmington, Delaware, but the results have not been announced.
Also this month, Apple Inc. denied allegations reported by state television that the location function on its iPhone might be a national security threat because it could allow access to confidential information. The company said it respected customers’ privacy and denied working with government intelligence services to create such “back door” access.
Managers of foreign technology companies complain regulators improperly use investigations and other administrative actions to hamper their operations and support domestic competitors.
Beijing has tried to compel foreign suppliers to disclose how encryption and other security technology work but backed down after complaints by the United States and other trading partners.
The government also is stepping up scrutiny of foreign companies and has cited its 2008 anti-monopoly law in ordering changes to acquisitions or business practices.
In June, the world’s three biggest container shipping operators — Denmark’s A.P. Moller-Maersk and MSC Mediterranean Shipping Co. SA and CMA CGM of France — scrapped a plan to create an alliance after Chinese market regulators objected.
Last August, five foreign milk suppliers and one in Hong Kong were fined a total of $108 million by anti-monopoly regulators on charges of price-fixing.
The government tries to support China’s fledgling suppliers by favoring them in procurement. Banks and major companies were ordered in 2010 to limit use of foreign security technology.
In May, the government announced it would examine imported technology for security flaws and ban products that fail. That came after U.S. authorities announced the indictment of five Chinese military officers accused of conducting cyber hacking of American companies.
