The president of the Federation of Restaurants said on Thursday that the easing of anti-pandemic measures could prevent more than two thousand eateries from going bust.
Simon Wong said he estimated that the move would allow restaurants to boost their business by "at least" 30-40 percent.
"There are about 3,000 restaurants on the verge of closing down," Wong told RTHK.
However, the new measures would allow 70 percent to 80 percent of these restaurants to survive, he said, adding that he hopes to see further easing soon.
Wong said the requirement for restaurants to have staff tested for Covid-19 every two weeks and to ensure that customers use the government's LeaveHomeSafe app, could prove to be a burden for business-owners, because it could lead to conflict with customers.
He also said that less than 10 percent of the population has downloaded the LeaveHomeSafe app, and called on more people to download the app, saying it was convenient and easy to use.
Wong urged the government to make it compulsory for people to use the app when they went shopping - not just when they visited a restaurant.
