Foxconn, Apple’s primary smartphone assembler, does the majority of its production at a plant in the central Chinese city of Zhengzhou, which has earned it the nickname of iPhone City.

China placed the 17.5 million residents of Shenzhen into lockdown for at least a week on Sunday, seeking to halt a growing Covid-19 outbreak. The lockdown, which came after virus cases doubled nationwide to nearly 3,400, will be accompanied by three rounds of citywide mass testing, according to a government notice. The move followed earlier restrictions placed on Shenzhen’s central business district.
All bus and subway systems have been shut, and businesses, except those providing essential services, have been closed. Shenzhen is home to the headquarters of giants Huawei Technologies Co., SZ DJI Technology Co. and Tencent Holdings Ltd. as well as one of China’s busiest ports.
