(Yicai Global) April 1 -- The area to the west of the Huangpu river in Shanghai, known as Puxi, is locking down from today to April 5 to carry out a new round of mass testing of 16 million people for Covid-19.

The city’s eastern half, called Pudong, has just finished testing its population and its next steps will depend on the results of those tests.
