China has put a city of 10 million people on lockdown over fears there will be another wave of coronavirus cases.
Harbin, the biggest city in Heilongjiang province, has banned all foreigners from entering residential zones.
More than 70 people have been infected and over 4,000 are being tested in Harbin after the virus was believed to be ‘imported’ into the city by a student who had returned from New York, according to media reports.
Officials have banned gatherings and ordered communities to closely monitor non-local visitors and vehicles.
Checkpoints have been installed at the airport and train stations, to screen those coming from elsewhere.
Before entering any public facilities and residential complexes, people must use a government-approved health app to prove they don’t have the virus, have their temperature taken and wear a face mask.
Residents must follow social-distancing measures. Weddings, funerals, public performances and conferences are banned.
The news comes as China announced that there were only two critically ill patients left in Wuhan, the former centre of the pandemic.
