TAIPEI (Reuters) - Apple supplier Foxconn expects to see full production resume at a COVID-hit China plant around late December to early January, a source with direct knowledge told Reuters on Monday, after unrest at a major iPhone factory in China's Zhengzhou.

The largest factory making Apple's iPhone has been grappling with strict COVID-19 restrictions that have fuelled discontent among workers and disrupted production ahead of Christmas and January's Lunar New Year holiday, as many workers were either put into isolation or fled the plant.

Foxconn declined to comment.
