China just can’t shake Covid. Nor can it shake its obsession with trying to stamp out the virus completely. Taken together, it spells trouble for the Chinese economy – and the world.

In recent days, Beijing has been heading the same way as Shanghai, which has endured a gruelling month-long lockdown, vocally opposed by many of its 25m residents. Weddings and funerals have been halted in the capital and schools have closed. It’s thought that 87 cities in China have been subject to some form of lockdown since the pandemic began.
