Exclusive: Chinese authorities conduct unannounced ‘inspections’ of Bloomberg News bureaus by Peter Elkind @FortuneMagazine December 2, 2013, 5:32 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons FORTUNE — In what appears to be a conspicuous show of displeasure, Chinese authorities conducted unannounced “inspections” at Bloomberg News bureaus in Beijing and Shanghai in the final days of November, Fortune has learned. The visits followed media reports that Bloomberg cancelled a year-long investigation on financial ties between a Chinese billionaire and government officials. Bloomberg has been described in press accounts as canceling the article to avoid antagonizing the Chinese government. According to those accounts—which are disputed by the company— Bloomberg News editor-in-chief Matt Winkler explained his decision to kill the story by comparing it to self-censorship in Nazi-era Germany, saying it would allow Bloomberg to avoid being expelled from China. Instead of soothing the government, Winkler’s reported comment appears to have stirred anger. During the visits, Fortune is told, at least one Chinese official asked the company for an apology from Winkler.

Details of the inspections, conducted on the same day at the news bureaus in Beijing and Shanghai, are sketchy. It’s unclear how many officials were present or what government agency they represented. Different sources say, variously, that the visits were characterized as “security inspections” or “safety inspections.” But journalists inside Bloomberg view the appearance by civil government officials (they weren’t police) as an act of intimidation — precisely the reaction Bloomberg was eager to avoid. Winkler referred questions to a company spokesman, who declined to comment. Last year, the Chinese government reacted strongly to an award-winning Bloomberg investigative series on the private wealth accumulated by the families of top public officials. China has refused to grant journalist visas to Bloomberg and, according to the New York Times, has ordered some companies not to lease Bloomberg terminals.
