HONG KONG— Foxconn Technology Group, the biggest assembler of Apple Inc. iPhones, said its factories in the Chinese manufacturing hub of Shenzhen were again running at full capacity Monday after the city wrapped up Covid-19 tests on all its 17 million residents.
But while Shenzhen returned to business as usual, more new cases in Jilin, Shanghai and other cities prompted tighter restrictions, highlighting the challenge that China still faces to contain its worst Covid-19 outbreak in two years.
