China: Ikea shoppers flee store as authorities attempt lockdown | A six-year-old boy had tested positive after returning to Shanghai from Lhasa in Tibet, Shanghai Health Commission deputy director Zhao Dandan said on Sunday. Authorities realised the boy had been one of the customers in the Xuhui district store and rushed to close it down and lock the rest of the shoppers inside. Health officials are under pressure to enforce China's 'zero-Covid' policy that places residents into quarantine if an online app says they tested positive.
