Shanghai cautiously pushed ahead with plans to restore part of its transport network in a major step towards exiting the weeks-long Covid-19 lockdown, while Beijing kept up its defences in an outbreak that has persisted for a month.

Shanghai’s lockdown since the beginning of April has dealt a heavy economic blow to China’s most populous city, stirred debate over the sustainability of the nation’s zero-Covid policy and stoked fears of future lockdowns and disruptions.

Unlike the financial hub, Beijing has refrained from imposing a city-wide lockdown, reporting dozens of new cases a day, versus tens of thousands in Shanghai at its peak.

As Beijing remained in Covid angst, workers in Shanghai were disinfecting subway stations and trains before planned restoration of four metro lines today.

While service will be for limited hours, it will allow residents to move between districts and meet the need for connections to railway stations and one of the city’s two airports.

More than 200 bus routes will also reopen.

Underlining the level of caution, Shanghai officials said commuters would be scanned for abnormally high body temperatures and would need to show negative results of PCR tests taken within 48 hours.

Shanghai found 868 new local cases on Friday, compared with 858 a day earlier, municipal health authorities said yesterday, a far cry from the peak in daily case loads last month. No new cases were found outside quarantined areas, down from three a day earlier, health authorities added.

The city of 25 million has gradually reopened shopping malls, convenience stores and wholesale markets and allowed more people to walk out of their homes, with community transmissions largely eliminated in recent days.

Still, Shanghai tightened stringent curbs on two of its 16 districts on Friday.

The authorities “urge enterprises to strictly implement safe production, which is their responsibility, especially in meeting some epidemic prevention and control requirements,” an official from the city’s emergency bureau said yesterday.
