After officials issued a partial lockdown owing to an increase in COVID-19 instances, Foxconn and other manufacturers are stopping operations in Shenzhen, China’s electronics capital. Following the discovery of 60 new infections on Sunday, businesses offering non-essential services have been forced to close, and everyone in the 17-million-strong city will be tested for COVID-19.

Foxconn is the world’s largest contract electronics manufacturer and a major supplier to firms such as Apple and Samsung. Shenzhen, which lies close the Hong Kong border, is home to several Chinese IT companies such as Huawei, Tencent, and Oppo. Foxconn has announced that production at its Longhua and Guanlan plants would be halted until further notice, according to Nikkei. Foxconn’s Shenzhen base is the company’s second largest in the country.

China has been steadfast in its efforts to contain the spread of COVID-19. Since the start of the pandemic, it has recorded a total of 4,636 fatalities and 115,466 confirmed cases. Shanghai, the country’s most populated city and home to major chipmaker SMIC, is also adopting additional restrictions as of today; buses to other provinces will be stopped, and everyone attempting to leave or enter the city will be forced to pass a negative PCR test. On Sunday, 64 additional COVID-19 cases were recorded in Shanghai.
