Hong Kong will ban the entry of all non-residents to the city for 14 days starting from Wednesday to contain the spread of COVID-19, Hong Kong Special Administrative Region Chief Executive Carrie Lam declared on Monday.

The announcement came amid growing pressure to contain the spread of COVID-19 in Hong Kong. The city reported 317 confirmed cases as of 4 p.m. on Sunday, with the majority of newly-confirmed cases having traveled abroad.

According to Lam, the Hong Kong airport will also stop all transit flights, and anyone entering from Macao or Taiwan must undergo 14 days of quarantine.

She urged people to strictly comply with the law, warning that the government will "tackle these cases severely" for people who breach the quarantine orders.
