(Bloomberg) -- Foreign companies in China are being subjected to cyber-security probes as the government tightens controls over areas such as cloud computing, the Financial Times reported, citing documents seen by the newspaper.

The government plans to strengthen its cyber rules in December to bolster “national information security,” the newspaper reported, citing the documents. The rules might be announced as soon as this week, the Financial Times said, citing people familiar with the matter.

The tightening of China’s so-called multilevel protection scheme is set to broaden government oversight of areas including the mobile internet, the internet of things, big data and industrial security, according to the documents, the newspaper said.

At least two foreign companies dealing with consumer data in China are already under investigation for possible cyber-security violations, the newspaper said, citing risk-management firm Control Risks. The names of the companies weren’t disclosed.

Morgan Stanley has opted to relocate about 150 back-office jobs from Shanghai, mostly to other parts of Asia, the Financial Times said. The bank declined to comment to the newspaper.
