Speaking on a radio program Thursday morning, Lo said although it has always been the arrangement to grant entry to unvaccinated mainlanders and vaccinated foreigners, authorities will study how the threshold can be unified as soon as possible. 

As to the question of whether the requirement will be adjusted to at least one dose of Covid vaccine or vaccine-free entry, authorities will make a decision after assessing all the risks, Lo said. 

On the other hand, Roundtable lawmaker Michael Tien Puk-sun suggested mandating travelers to be fully inoculated against Covid before coming to Hong Kong, no matter where they come from, as he added that the coronavirus “does not discriminate against anyone.” 

Tien said so as he attended a separate radio program this morning, saying that he objected to canceling the vaccine pass scheme. 

He further explained that as border points between Hong Kong and the mainland reopen, mainlanders entering restaurants without vaccination may bring pressure onto the SAR's healthcare system. 

He continued that if mainland asks arrivals for a negative PCR test result valid for 48 hours before entry, Hong Kong should do the same so as to keep the arrangement bilateral and equal.
