BEIJING—Access to an industrial zone in the central Chinese city of Zhengzhou was suspended Wednesday after the city reported 64 coronavirus cases and workers who assemble Apple Inc. iPhones left their factory in the zone following outbreaks.
The announcement did not say whether the isolation of the Zhengzhou Airport Economic Zone was related to cases at the Foxconn factory. It gave no indication of what prompted the closure. It said no one can enter or leave for one week except to deliver food and medical supplies.
