Delta variant tests China’s virus lockdown strategy

CHINATOPIX people is prompting warnings that China needs to learn to control the virus without repeatedly shutting down the economy and society.

Zhang Wenhong, a Shanghai doctor who became prominent during the Wuhan outbreak, suggested in a social media post that China’s strategy could change. “We will definitely learn more” from the ongoing outbreak, he said, calling it a stress test for the nation.

“The world needs to learn how to coexist with this virus,” wrote Zhang, who has 3 million followers on the widely used Sina Weibo platform.

China’s controls will be tested when thousands of athletes, reporters and others arrive for the Winter Olympics in Beijing in February. And the ruling party faces a politically sensitive change of leadership in late 2022, for which leaders want upbeat economic conditions.

Last year, China shut down much of the world’s second-biggest economy and cut off almost all access to cities with a total of 60 million people — tactics imitated on a smaller scale by governments from Asia to the Americas. That caused China’s most painful economic contraction in five decades, but Beijing was able to allow business and domestic travel to resume in March 2020.

The new infections, many in people who have already been vaccinated, have jolted global financial markets, which worry Beijing’s response might disrupt manufacturing and supply chains.

China needs to shift to creating barriers to infection within communities by stepping up vaccinations and quickly treating infected people while allowing business and travel to go ahead, said Xi Chen, a health economist at the Yale School of Public Health.

“I don’t think ‘zero tolerance’ can be sustained,” said Chen. “Even if you can lock down all the regions in China, people might still die, and more might die due to hunger or loss of jobs.”

But Beijing has shown no sign of abandoning its tactics.
