China's financial centre Shanghai reported a new record number of symptomatic Covid-19 cases on Saturday as the country imposed new lockdowns, underscoring its “dynamic clearance” approach to Covid control.

According to Reuters, the Zhengzhou Airport Economic Zone, an industrial area in the central province of Henan that houses manufacturing facilities of companies including Apple Inc supplier Foxconn, announced a 14-day lockdown on Friday “to be adjusted according to the epidemic situation.” Foxconn is the trade name of Hon Hai Precision Industry Co Ltd.

Only personnel with valid passes, health codes and proof of negative Covid tests will be able to leave the zone during the period, though “special vehicles” will be able to travel normally for work reasons, economic zone authorities said in a post on an official WeChat account.

The announcement came as the northwestern city of Xian said it would temporarily impose a partial lockdown on its 13 million residents following dozens of Covid-19 infections this month.
