Hong Kong will prioritize quarantine-free travel for business people when its China border reopens, Chief Executive Carrie Lam Cheng Yuet-ngor said, warning that the city’s vaccination rate could curb a broader roll-out.

“If we cannot raise our vaccination rate, it will be a hindrance to expanding our border reopening plan,” Lam said at a regular press briefing on Tuesday.

Only 61 percent of the city’s people have been fully inoculated, according to Bloomberg’s Covid-19 Vaccine Tracker -- far behind Singapore’s 88 percent figure.

The government is working to set quotas for business people in different sectors to prepare for central authorities confirming when quarantine-free travel can resume, Lam said.
