Police detain pro-democracy protesters during a rally at a shopping mall in Hong Kong, China, on June 30, 2020.
Details of the law - which comes in response to last year's often-violent pro-democracy protests in the city - are due out later on Tuesday.
The legislation will come into effect when it is gazetted in Hong Kong - bypassing the semi-autonomous territory's own legislature - and is expected to be in force by July 1, the anniversary of the former British territory's return to Chinese rule.
"We hope the law will serve as a deterrent to prevent people from stirring up trouble," said Tam Yiu-Chung, Hong Kong's sole representative on the Standing Committee of the National People's Congress, which approved the law on Tuesday morning. "Don't let Hong Kong be used as a tool to split the country," he said.














Comment: Doom and gloom? Or an overblown reaction to anything Beijing? Something had to give.
