No date given for end of extended lockdown in city that is a crucial supplier of Apple products

Chengdu, the capital of the south-western Chinese province of Sichuan, has extended the coronavirus lockdown of most of its districts indefinitely as it hopes to stem further transmissions in the city of 21.2 million.

The mega city, which has most recently battled with heatwaves, power cuts and an earthquake, was locked down on 1 September after detecting a number of cases, becoming the largest Chinese metropolis to be slapped with the curbs since Shanghai earlier this year.
