The quarantine policy also applies to travelers from Australia - excluding Victoria state - mainland China, Malaysia and Chinese Taiwan, Singapore officials told reporters on Friday, AFP reported.

They said the city-state will allow travelers from Brunei and New Zealand to visit from September. The visitors will have to be tested for the novel coronavirus, but will be exempted from the 14-day quarantine.

Transport Minister Ong Ye Kung said Brunei and New Zealand were chosen as they are small countries and have controlled the virus well.

Singapore closed its borders in March to tourists and short-term visitors. It has reported more than 56,000 COVID-19 infections and 27 deaths.
