Life and business will return to normal in Shanghai between June 1 and mid-to-late next month as the COVID-19 pandemic has been effectively controlled, Shanghai Vice Mayor Zong Ming announced on Monday.

"The city's pandemic has been put under effective control, though the risk of a resurgence still exists," Zong told the city's daily coronavirus press briefing.

Fifteen of the city's 16 districts have achieved zero community transmission, while the population within the locked-down areas has dropped to under a million.
