Why China Is Still Imposing Lockdowns

The world has moved on from the coronavirus pandemic—except for China. Chinese leaders continue to lock down some of the country’s largest cities, spend millions of dollars on testing, and hunt down individual case after individual case. Nothing—neither a sinking economy nor the availability of vaccines and improved treatments nor the country’s growing isolation—has persuaded the leadership to change course. The latest wave of lockdowns has largely confined millions to their homes: Just two of those lockdowns, involving the southwestern metropolis of Chengdu and the tech hub of Shenzhen, affected a combined population roughly equivalent to all of Canada’s.
