SHANGHAI (Bloomberg): China’s Covid-19 outbreak is shifting to its south coast, with a flareup in technology hub Shenzhen triggering mass testing and a lockdown of some neighbourhoods, while gambling enclave Macau -- an hour’s drive away -- is racing to stop its first outbreak in eight months.

The new cases come as China’s two most important cities, Beijing and Shanghai, look to be subduing the virus after months of strict curbs and repeated testing.
