Apple manufacturing partner Foxconn is gradually resuming production at a key complex in the central city of Zhengzhou that was closed because of the new coronavirus outbreak. But it is only allowing workers from the surrounding province of Henan to return to work.

More than 6,600 workers from less-affected areas of Henan are allowed to restart work without quarantine, while those from more-impacted places are subject to a 14-day quarantine at home before working. Returnees from regions moderately affected by the disease need to obtain health certificates before getting back to work.

Foxconn is also restarting its recruitment drive for the Zhengzhou factory, but said it is currently only considering job applicants from “slightly” and “moderately” impacted places of Henan province as the epidemic has not been completely brought under control. A successful candidate will be rewarded with a cash bonus of 5,250 yuan ($746), according to the company.

The limited restart of production in Zhengzhou comes after Henan authorities announced they would gradually resume the province’s public transport operations from Feb. 21.

The Zhengzhou complex is Foxconn’s main iPhone-assembly facility and produces more than 40% of Apple’s iPhones worldwide.

On Monday, Apple warned that it will miss a previous first-quarter revenue forecast due to the slower-than-expected resumption of production by its Chinese suppliers.
