China’s strategy to fight the Covid-19 pandemic has a proven track record. Termed “dynamic zero”, it has kept the numbers of infections and deaths low compared to other countries.

Despite that, the policy has been increasingly facing criticism from others, including World Health Organization director general Tedros Adhanom Ghebreyesus, who labelled it unsustainable. But such pressure is not warranted given that each nation has its own circumstances and the approach Beijing has tried, tested and refined is based on science and time and again has been shown to be effective.

Ghebreyesus said on Tuesday that the United Nations health body believed China should change its approach given “the behaviour of the virus and what we now anticipate in the future”. Many countries are easing controls, determining the worst of the pandemic is over.

But large parts of Shanghai, China’s most populous city and financial centre, remain locked down for a sixth week and residents of the capital, Beijing, have been undergoing repeated testing. Inevitably, policies that involve stopping the movement of people, quarantining those considered at risk and taking the infected to hospital when they exhibit no symptoms, are perceived by some as archaic.

Authorities face rising criticism, particularly from the West and businesspeople, over the perceived economic and social costs of the approach. But it is not a rigid strategy and allows flexible responses to prevent outbreaks in line with local situations. The common goal is to stop serious infection and death. Oversimplifying what it means is bound to lead to misunderstanding.

The highly transmissible Omicron variant of the coronavirus and the threat of new strains are reasons for caution. A recent Chinese-American study determined that abandoning controls may result in about 1.5 million deaths in China from Omicron infections. That explains why President Xi Jinping last week said the nation had to stand firm and not waver in the face of the continued threat. No two countries can claim to have the same conditions; tolerance for death and infection varies, as do levels of healthcare and types of vaccination and treatment.
