In an interview with China Central Television broadcast on Friday, Hong Kong's Commissioner of Police Chris Tang Ping-keung said the legislation can effectively prevent and contain activities that endanger national security, such as terrorism, sabotage and forces advocating "Hong Kong independence".

It will help restore social order and make Hong Kong a safer and more stable city, Tang said.

The police will maintain close communication with government departments and relevant institutions in the SAR to ensure the accurate and effective implementation of the legislation to safeguard national security, he added.

Richard Cullen, an Australian visiting law professor at the University of Hong Kong, told China Daily that he believes the legislation will contribute to Hong Kong's stability and development based on the successful experience of Macao and Singapore, where similar laws in practice have created more favorable conditions for business activity.

"Having robust national security laws and enforcement is not at all incompatible with having a business-friendly society," Cullen said.

He also expressed confidence that the law will not undermine the legitimate rights and freedoms of Hong Kong residents, given the city's well-established legal system.
