It grants the police powers to control and remove online information if there are “reasonable grounds” to suspect the data breaches the national security law — reminiscent of internet controls in mainland China.
Internet firms and service providers can be ordered to remove information, and their equipment can be seized.

Despite concerns about how it collects and shares data, TikTok has become a global sensation with users — especially young people — sharing 15 to 60-second video clips on everything from hair dye tutorials to dance routines and gags about daily life.
While it does not publish such data, TikTok is estimated to have close to a billion users worldwide.
But it has also found itself involved in major diplomatic disputes.
India banned TikTok over national security concerns following a deadly border clash between its soldiers and Chinese forces.
And US Secretary of State Mike Pompeo has said Washington is also looking at banning Chinese social media apps including TikTok over allegations that they are being used to spy on users.
Despite its ownership, TikTok is not available in mainland China, where ByteDance offers a variant called Douyin.
