Covid-19 cases climb in China

Beijing: Chinese authorities on Tuesday tightened anti-virus controls at ports, raising the risk of trade disruptions after some auto and electronics factories shut down as the government fights coronavirus outbreaks.

China’s Covid-19 case numbers are low compared with other major countries. But local authorities are enforcing a “zero tolerance” strategy that aims to keep out the virus. It has temporarily shut down major cities to find every infected person.
