BEIJING (AP) — Thousands of coronavirus testing sites have popped up on sidewalks across Beijing and other Chinese cities in the latest development in the country’s “zero-COVID” strategy. Regular testing of residents is becoming the new normal as the ruling Communist Party sticks steadfastly to the “zero-COVID” approach that is increasingly at odds with the rest of the world. The move follows a recent outbreak in Shanghai that spread so widely that authorities locked down the entire city for two months to end it. Authorities have decided that early detection is needed if they are going to control omicron outbreaks without extreme measures that cause major economic disruption.
