As most of the world learns to live with COVID-19, China is tethering itself to eliminating the virus over the long term — an approach that risks leaving the world’s second-biggest economy isolated for years to come.

China this month saw the contagious delta variant pop up in more than half of 31 provinces despite water-tight border controls, triggering yet another round of targeted lockdowns, travel curbs and mass testing across the country. While the outbreak is the most widespread in China since the initial flare-up in Wuhan last year, the World Health Organization said total cases last Friday were 141 — around .01% of the new infections that day in the U.S.

The aggressive moves to tame a relatively small caseload in a country with one of the world’s highest vaccination rates shows how politically invested the Communist Party has become in achieving zero COVID-19 infections. Chinese authorities are increasingly trumpeting their success in containing the virus as an ideological and moral victory over the U.S. and other nations now treating COVID-19 as endemic.
