This came as Hong Kong has seen no new local case for 13 consecutive days, with only one imported case from Russia today, taking the SAR's tally to 11,887 including 210 deaths.

Three factors will be taken into consideration – development of the outbreak, vaccination rates and the implementation of “vaccine bubble” at restaurants and premises, Cheung said.

The first stage of "vaccine bubble" policies have been put in place since April 29 to relax social distancing measures at restaurants according to four operation models according to inoculations in workers and customers.

Closed premises including bars, nightclubs and karaoke lounges were also allowed to reopen but they can only cater to vaccinated patrons.

Announcing more relaxed measures under the "vaccine bubble" on May 31, authorities said it will allow up to 12 customers sharing a restaurant table, if two-thirds of them have been vaccinated while the rest are unfit for the jab due to their age and health conditions.
