HONG KONG — The company that assembles Apple Inc.’s iPhones has announced it is easing COVID-19 restrictions at its largest factory in China that led thousands of workers to quit and drastically slowed production.

Foxconn Technology Group said in a statement on one of its official WeChat social media accounts that it would end the so-called closed loop system at the facility in Zhengzhou, central China, that required workers to stay in their workplaces and dormitories to prevent the spread of coronavirus infections.

The move announced Wednesday came about a week after China began easing harsh COVID-19 curbs despite signs the number of infections is rising.
