Liberal Party leader Felix Chung is urging the government to offer financial assistance to all business sectors in the city due to the current virus outbreak, and not just those it announced help for last Friday.
The administration is to provide subsidies to shops, restaurants and travel agencies as part of a HK$25 billion package which will also see payments for low-income families and students.
But Chung says he also wants the government to help a wide variety of businesses pay off their bank loans.
"The amount that is being given out is only for certain industries, just like the tourism, retail and catering. But other sectors are also having difficulties and also need subsidies from the government," Chung told RTHK's Janice Wong.
"For example, if you think about the export business. A lot of people think that is not affected because the international market is not affected that badly. But most of the factories in China are still closed. They cannot open to start production."
Chung said he would tell Financial Secretary Paul Chan that he should help companies pay off their loans during the current downturn.
He said he also thinks everyone in Hong Kong should benefit from either cash handouts or coupons, adding that the government can easily afford this with its massive reserves.
The Democratic Party has suggested HK$10,000 handouts for all residents, and Chung said he backs this proposal.
