The Hong Kong government on Thursday said it strongly disapproves of, and condemns all baseless allegations by the United States Congressional-Executive Commission on China (CECC) and the European Union (EU) against the city’s homegrown national security law as well as law enforcement action taken by the police’s National Security Department.

The police made seven arrests on Tuesday and Wednesday on suspicion of "offences in connection with seditious intention" under the Basic Law Article 23 national security legislation.

One of the arrestees was former vice-chairwoman of the now-defunct Hong Kong Alliance, Chow Hang-tung.

The seven were accused of being responsible for seditious posts published on social media ahead of what authorities described as a "sensitive date".

The CECC and EU had described the arrests as a violation of human rights and an attempt to stifle freedom of expression.

But in a statement published on Thursday, authorities said their claims simply do not stand up to the facts.

“The HKSAR law enforcement agencies have been taking law enforcement actions based on evidence and strictly in accordance with the law in respect of the acts of the persons or entities concerned, and have nothing to do with their political stance, background or occupation,” the statement wrote.

“Offences in connection with seditious intention are very serious crimes, and no jurisdictions, including the US and those from the EU, will watch with folded arms acts and activities that endanger national security.”

The government stressed Hong Kong’s homegrown national security ordinance only targets an extremely small minority of people who endanger national security, adding that it will not hinder legitimate expression of opinions.

“The Ordinance is a piece of legislation to defend against acts and activities endangering national security. Only invaders who want to intrude into our home to plunder and loot should be worried by the Ordinance,” the statement added.
