Abrupt End of Zero-COVID Policy
After nearly three years of strict pandemic controls, China dismantled its zero-COVID policy within days, removing testing requirements, quarantine mandates, and travel restrictions; the policy adjustment triggered a large-scale Omicron wave that independent epidemiological estimates suggest caused over one million deaths.
Three Years of Zero-COVID
From early 2020 until late 2022, China pursued a zero-COVID strategy of suppressing all outbreaks through mass testing, contact tracing, mandatory quarantine, and targeted lockdowns. The strategy was held up as a national success compared to Western countries' high death tolls, and Xi Jinping personally associated himself with its implementation. By 2022, however, the highly transmissible Omicron variant made elimination increasingly costly: Shanghai's two-month lockdown in spring 2022 caused significant economic and social disruption.
The Abrupt Reversal
Following the November 2022 White Paper Protests, the government dismantled the zero-COVID system within days. On December 7, 2022, the National Health Commission announced an end to mandatory quarantine for positive cases and removal of most testing requirements. By December 26, COVID was downgraded from a Class A to Class B infectious disease, removing the legal basis for most restrictions. The change was implemented without publicly announced communication strategies, epidemic preparedness plans for the expected surge, or transition arrangements.
The Omicron Wave
The transition resulted in a massive Omicron wave hitting an under-vaccinated (particularly among the elderly) and immunologically naive population. Chinese authorities stopped reporting daily case figures as infections surged. Hospitals, funeral homes, and crematoriums were overwhelmed. Independent estimates based on excess mortality and epidemiological modelling suggested between 1 and 1.5 million deaths in the months following reopening — a toll the Chinese government has never officially acknowledged.
Narrative Comparison
| Source | Narrative |
|---|---|
| Chinese Official Position | The optimisation of control measures was an active, science-based decision made in response to viral mutation characteristics, the evolving epidemic situation, and domestic and international prevention experience, reflecting the "people-centred" governing philosophy; the policy goal had always been to protect people's lives and health to the greatest extent. |
| Western Media and Observers | Reuters, the BBC, The New York Times and several public health scholars argued that the policy was ended without adequate transition preparation, placing significant pressure on the healthcare system in a short period. Analysts noted the close timing between the policy shift and the White Paper Protests, and questioned the official "scientific assessment" explanation given the government's previous long-standing commitment to zero-COVID. Independent studies based on excess mortality data estimated a death toll higher than official figures. |
Key Milestones
- State Council Joint Mechanism Issues "Ten New Measures"
The State Council's joint prevention and control mechanism issued a notice removing routine mass testing requirements, ending mandatory centralised quarantine, permitting eligible positive cases to isolate at home, and restoring freedom of movement across regions.
- COVID-19 Downgraded to Class B Infectious Disease
The National Health Commission announced that from 8 January 2023, COVID-19 would be reclassified from a Class A to a Class B infectious disease, removing the legal basis for most mandatory COVID control measures.
- Entry Quarantine Requirements Lifted, International Travel Fully Resumed
China removed COVID testing and quarantine requirements for inbound travellers and fully resumed international travel, ending the border control measures that had been in place since January 2020.
