SHANGHAI (REUTERS) - Shanghai set out plans on Monday (May 16) for the return of more normal life from June 1 and the end of a painful Covid-19 lockdown that has lasted more than six weeks and contributed to a sharp slowdown in China’s economic activity. 

In the clearest timetable yet, Deputy Mayor Zong Ming said Shanghai’s reopening would be carried out in stages, with movement curbs largely to remain in place until May 21 to prevent a rebound in infections, before a gradual easing.

"From June 1, to mid- and late June, as long as risks of a rebound in infections are controlled, we will fully implement epidemic prevention and control, normalize management, and fully restore normal production and life in the city," she said.  

But the announcement was met with scepticism by some Shanghai residents, who have been disappointed time and again by shifting schedules for the lifting of restrictions.  

"Shanghai, Shanghai... am I still supposed to believe you?" one member of the public said on the Weibo social media platform.

The full lockdown of Shanghai and Covid curbs on hundreds of millions of consumers and workers in dozens of other cities have hurt retail sales, industrial production and employment, adding to fears the economy could shrink in the second quarter.  

The restrictions, increasingly out of step with the rest of the world, which has been lifting Covid rules even as infections spread, are also sending shockwaves through global supply chains and international trade.  

Data on Monday showed China’s industrial output and retail sales fell in April at the fastest in more than two years, missing expectations.

Recent data has been bleak: catering revenue sank 22.7 per cent; auto sales crashed 47.6 per cent; property sales by value slumped 46.6 per cent.  

Economic activity has probably been improving somewhat in May, analysts say, and the government and central bank are expected to deploy more stimulus measures to speed things up. 

But the strength of the rebound is uncertain due to China’s uncompromising "zero Covid" policy of eradicating all outbreaks at all costs.  

"The data paint a picture of a stalling economy and one in need of more aggressive stimulus and a rapid easing of Covid restrictions, neither of which are likely to be forthcoming anytime soon," said Mitul Kotecha, head of emerging markets strategy at TD Securities.  

China’s weaker growth would "fuel a further worsening in global economic prospects", he said.  

The data overshadowed Shanghai’s reopening plans, sending Chinese stocks lower.

In Beijing, the discovery of dozens of new Covid-19 cases every day for the past three weeks shows how difficult it is to eliminate even small outbreaks.

The capital has not enforced a city-wide lockdown but has been tightening curbs to the point road traffic levels in Beijing slid last week to levels comparable to Shanghai’s, according to GPS data tracked by Chinese internet giant Baidu.  

On Sunday, Beijing extended guidance to work from home in four districts. It had already banned dine-in services at restaurants and curtailed public transport, among other measures. 

Videos circulating on social media overnight showed some students at Peking University demanding the removal of fences put up around some dormitories to block Covid. Reuters was unable to immediately verify the authenticity of the videos.

In Shanghai, the deputy mayor said the city would begin to re-open supermarkets, convenience stores and pharmacies from Monday, but that many movement restrictions had to remain in place until at least May 21.  

It not clear how many businesses have reopened.  

From Monday, China’s railway operator will gradually increase the number of trains arriving and departing from the city, Mr Zong said. Airlines will also increase domestic flights.  

From May 22, bus and rail transit will also gradually resume operations, but people will have to show a negative Covid-19 test not older than 48 hours to take public transport.

Throughout the lockdown, Shanghai has had to repeatedly dash hopes for an end to the ordeal. Authorities expected it to only last until April 5 when it was introduced on March 27.

Last week, many residential compounds got notices that they would be in "silent mode" for three days, which typically means not being able to leave the house and, in some cases, no deliveries. Another notice then said the silent period would be extended to May 20.  

"Please don’t be lying to us this time" one member of the public said on the Weibo social media platform, adding a crying emoji.  

Shanghai reported fewer than 1,000 new cases for May 15, all inside areas under the strictest controls.  

In relatively freer areas, the ones monitored to gauge progress in eradicating the outbreak, no new cases were found for a second day in a row.  

A third day would usually mean "zero Covid" status has been achieved and restrictions can begin to ease. Fifteen of the city’s 16 districts had reached "zero Covid".  

Beijing reported 54 new cases, up from 41.
