Security Law Must Be Imposed Without Delay: Wang Yi

A controversial security law for Hong Kong proposed by Beijing during its national legislative session should be imposed "without the slightest delay", foreign minister Wang Yi said on Sunday.

The proposal is expected to ban treason, subversion and sedition, and comes after Hong Kong was shaken by months of massive and sometimes violent anti-government protests.

Wang told a press conference that the law was "imperative" after protests in the semi-autonomous hub last year "seriously endangered China's national security".

The draft measure would authorise Chinese lawmakers to directly enact controversial security legislation long called for under Hong Kong's mini-constitution but which authorities in the city have been unable to push through due to local public opposition.

"It is imperative that the Hong Kong national security legal system and enforcement mechanism must be established without the slightest delay," Wang said.

He told reporters covering the week-long legislative session that "violent and terrorist activities are continuing to escalate, (and) foreign forces have deeply and illegally interfered in Hong Kong affairs."

Wang also said the new legislation would target a narrow category of acts and would have no impact on the city's freedoms or rights, or interests of foreign firms.

He said instead of being more worried, people should be more confident of stability of Hong Kong.

Hong Kong's unpopular leader Carrie Lam said in a statement on Friday that the new proposal was necessary to protect national security and punish "violent political elements".
