The city has been hit hard by the restrictions as it was under a stringent lockdown for almost two months. Plans have also been drawn to support the city's economy.

The announcement in Shanghai came as official figures showed on Sunday that new daily coronavirus cases fell to 122 from 170 over the previous 24 hours, BBC said in its report.

Guidelines to restrict the virus's spread and control the number of people returning to work will also be revised, according to officials.

The move will see "unreasonable restrictions" being lifted on restarting work and production at companies,

BBC quoted vice mayor Wu Qing as saying that the companies will no longer need to be on a "whitelist" to resume production starting from June 1.

Meanwhile, in Beijing, parts of public transport system, shopping malls and other venues have been reopened with the decline in Covid cases.
