Big technology companies may already be complying with secret Chinese requests for user information held in Hong Kong and ought to “come clean” about the vulnerability of the data they hold there, a senior US state department official has said.

The allegation of possible secret cooperation between major companies and Hong Kong authorities follows the implementation of a sweeping and controversial new national security law that allows Hong Kong authorities to demand sensitive user data from companies if it is deemed to threaten national security.

While some tech and social media companies, like Facebook, Google, and Microsoft, said in the immediate aftermath of the law being implemented in June that they would put a “pause” on complying with any Hong Kong data requests, interviews with activists, legal experts, and a current and former US government official have raised doubts about their ability to fend off such legal demands and their right to disclose if they have received them.
