After months of imposing limited lockdowns of individual neighbourhoods, Shanghai has decided to lock down parts of China’s biggest city in two phases in a bid to curb a spike in Covid-19 infections. The measures started on March 28, 2022, with restrictions on a zone from the eastern bank of the Huangpu River, including the Pudong New Area that is home to about 5.7 million people. After the first lockdown ends on April 1, the west bank of the city will be locked down.
