Beijing has gone on an alert mode following a sudden spike in COVID-19 cases in the neighbouring Hebei province while China has administered nine million coronavirus vaccines so far in a stepped-up nationwide drive to contain the virus.
The National Health Commission (NHC) on Saturday reported 33 newly confirmed COVID-19 cases, of whom 17 were locally transmitted and the rest arrived from outside the mainland.
Fourteen locally transmitted cases were reported in north China's Hebei province, the NHC said.
The rise of cases in Hebei sent Beijing on alert as the capital, besides housing the country's top leaders, is getting ready for the annual Parliament session from March 5 during which over 5,000 legislators and advisers would converge.
Beijing has already announced 21-day quarantine for people coming from abroad.
Alert levels in Beijing have gone up as Hebei reported 14 new locally-transmitted cases and 16 asymptomatic ones on Friday.
