Beijing COVID outbreak prompts fear of Shanghai-style lockdown

WATCH: China cracks down on COVID outbreak in Beijing

A new COVID-19 outbreak in Beijing is raising fears that China’s capital could be sent into a hard lockdown, like the one in Shanghai that’s entering a fifth week.

Beijing residents are stocking up and clearing shelves, despite authorities telling residents there are enough supplies to go around.

About 3.5 million residents in Beijing’s affluent Chaoyang district, which includes the central business district, will have to undergo mandatory mass testing three times this week to contain a spike in cases, with 70 infections reported citywide there since Friday.

China's daily cases rose 4% to 20,194 on Monday, most of them in Shanghai. The city has now recorded 506,000 infections since the start of March.
