China is redoubling efforts to control new virus outbreaks with a lockdown of the 13 million residents of the northern city of Xi’an following a spike in coronavirus cases.
The measure comes just weeks before the country hosts the Winter Olympics in Beijing, roughly 621 miles to the west.
There was no word on whether the virus was the newly surging omicron variant or the far more common delta.
China has recorded just seven omicron cases: four in the southern manufacturing centre of Guangzhou, two in the southern city of Changsha and one in the northern port of Tianjin.
China has also been dealing with a substantial outbreak in several cities in the eastern province of Zhejiang near Shanghai, although isolation measures there have been more narrowly targeted.
Authorities have adopted strict pandemic control measures under their policy of seeking to drive new transmissions to zero, leading to frequent lockdowns, universal masking and mass testing.
While the policy has not been entirely successful, leading to massive disruptions in travel and trade, Beijing credits it with largely containing the spread of the virus.
The Xi’an restrictions are some of the harshest since China in 2020 imposed a strict lockdown on more than 11 million people in and around the central city of Wuhan, where the coronavirus was first detected in late 2019.
Xi’an on Thursday reported another 63 locally transmitted cases, pushing the city’s total to at least 211 over the past week.
Xi’an is the capital of Shaanxi province, famed for its imperial relics, as well as a major centre of industry.
“We are not receiving any new guests and no present guests are allowed to leave the hotel,” said a receptionist at the Hanting Hotel in Xi’an, who only gave her surname, Li.
“Including the guests, we are required to take a test once every two days,” Li said. “There will be an impact on our business and we have no idea how long it will last.”
The owner of a local bookshop said he had closed 10 days before “fearing the worsening of the epidemic situation”.
“I am now staying at home watching television,” said the owner, who gave only his surname, Xiao.
Movement outside his premises required permission from the local neighbourhood committee, he said.
“I think the situation will get better eventually, and I don’t worry at all because we have the government behind us,” Xiao said.
One person from each household will be allowed out every two days to buy household necessities, a government order said. It took effect at midnight Wednesday, with no word on when it might be lifted.
China has reported 4,636 deaths among a total of 100,644 cases of Covid-19.
