China has begun to ease COVID-19 restrictions in some of its largest cities. On Monday, workers in two districts of the capital Beijing were allowed to return to offices after authorities lifted some work-from-home rules and reopened public transit. Meanwhile, officials in Shanghai say they’re preparing to lift a strict two-month lockdown on June 1. Chinese President Xi Jinping has ruled out ending China’s “zero-COVID” strategy as the nation struggles to stamp out its worst wave of coronavirus infections since early 2020.
