Zhengzhou, capital of central Henan province, reported 167 locally transmitted COVID-19 cases in the seven days to Oct. 29, up from 97 infections in the prior seven-day period.

Apple (AAPL.O) supplier Foxconn, based in Taiwan, currently has about 200,000 workers at its Zhengzhou complex and has not disclosed the number of infected workers, but said on Sunday that it would not stop workers from leaving.

Late on Saturday, cities near Zhengzhou, including Yuzhou, Changge and Qinyang, urged Foxconn workers to report to local authorities in advance before heading home.

Returning workers are to travel "point-to-point" in pre-arranged vehicles and are to be quarantined on arrival, they said in separate letters on their respective social media accounts addressed to Zhengzhou Foxconn workers.

Under China's ultra-strict zero-COVID policy, cities are mandated to act swiftly to quell any outbreaks, with measures that could include full-scale lockdowns. On Oct. 19, Foxconn banned all dine-in at canteens and required workers to take their meals in their dormitories.

"The government agreed to resume dine-in meals to improve the convenience and satisfaction of employees' lives," Foxconn told Reuters in an emailed reply to queries on Sunday.

"At the same time, for some employees who want to return home, the (plant) is cooperating with the government to organise personnel and vehicles to provide a point-to-point orderly return service for employees from today."

Disruptions from China's COVID policies to commerce and industry have intensified in recent weeks as cases multiplied. Shanghai Disneyland said on Saturday it would operate at reduced capacity. On Wednesday, Universal Beijing Resort was suspended after the visit of one infected individual.

"We are very aware that under the current situation, it is a protracted battle," Foxconn said.

But the situation was gradually coming under control, it said, and Foxconn would coordinate back-up production capacity with its other plants to reduce any potential impact.

Apple did not immediately reply to a Reuters request for comment on the Foxconn situation.

'I COULDN'T HELP BUT FEEL SAD'

Foxconn did not respond to Reuters questions on how many cases had been detected at its Zhengzhou plant and how many workers had left.

Photographs and videos circulating on Chinese social media since Saturday showed Foxconn workers, apparently returning home, trekking across fields in the day and along roads at night. Reuters could not immediately verify the authenticity of the posts.

In a show of support, residents in the vicinity left bottled water and provisions next to roads with signs such as: "For Foxconn workers returning home", according to social media posts.

"Some people were walking amid wheat fields with their luggage, blankets and quilts," wrote a user of WeChat in a post about the social media images.

"I couldn't help but feel sad."
