Her remarks come roughly a week after police detained seven people linked to the pro-democracy online news organization Stand News on charges of sedition, prompting the outlet to shut down. Another online news site, Citizen News, announced its closure a few days later. "We didn't do anything for any of the media outlets." Law enforcement agencies never addressed them," Lam said at a press briefing on Tuesday. "However, if they opted to stop operating due to their own worries, I don't believe this is unusual."" She went on to say that the Hong Kong government does "not to stifle freedom of the press." Lam stated that Hong Kong's government adheres to the rule of law, and that when she first took office, she invited online news outlets to government press conferences and met with the Hong Kong Journalists Association. "News outlets can continue to report news in Hong Kong as long as they do not engage in criminal conduct," Lam stated. Since the city's National Security Law was implemented in June 2020, she added, local news outlets registered in the city have increased by 5.4 percent, while abroad outlets have increased by 9.4 percent. Over a hundred people have been jailed since the security law went into effect, including numerous pro-democracy activists and journalists who previously worked for the now-defunct Apple Daily and Stand News. Separately, Lam announced on Tuesday that the city will tighten vaccination regulations to include not just entertainment facilities, but also libraries, schools, and museums. From February 24, the mandate would be reinforced, requiring those entering such venues to have at least one dose of COVID-19 vaccine. The vaccine mandate was expanded just days after Hong Kong revealed its first omicron COVID-19 cluster, which was linked to numerous Cathay Pacific crew members who had breached isolation regulations and visited restaurants and pubs throughout the city before being tested.
