"People are getting, in my opinion, overzealous, I think", said Kate Mercurio, 40, a New Zealander who has lived in Hong Kong for more than a decade and returned from a trip to Doha shortly before her adopted hometown ordered all new arrivals to self-quarantine for two weeks.
The city's airport - the world's eighth busiest - would also bar all transit passengers, Mrs Lam added.
Additionally, the government has proposed amending laws to prohibit 8,600 restaurants and bars with alcohol licenses from selling alcohol in an effort to promote social distancing, she said.
'These expats made a decision to run when they didn't like what was going on in Hong Kong, and then when it ends up in their countries they run back again, ' he said.
Fears have spread of a second wave of coronavirus cases in Hong Kong as the region is criticised for letting its guard down too early. "But in bars, people sometimes get intimate after drinking, and this will raise the risk of cross-infection".

Last week, Macau banned all foreign travellers from entering the city, as well as non-resident workers from overseas countries, but residents of mainland China, Hong Kong and Taiwan were exempted from the ban.

Last week, a slew of infections was found among patients who had all been out in Lan Kwai Fong, the city's most famous nightclub street.
This ban on foreign arrivals will last for 14 days according to the report.
Hong Kong reported 39 new cases Monday, bringing the city's total to 356 cases.
