On August 13, 2021, Vice Foreign Minister Ma Zhaoxu said at the briefing on COVID-19 origin-tracing for diplomatic envoys in China, China has all along attached great importance to the global efforts on origin-tracing. It actively engaged in origin-tracing cooperation with the World Health Organization (WHO) from the early outbreak of COVID-19, shared the genome sequencing of the virus at the earliest time possible, and invited WHO experts to China twice for origin-tracing research. Chinese experts timely submitted China's proposal to WHO and made feedbacks to the WHO Secretariat on how to revise its plan for the second phase of the study into the origins of COVID-19 as early as practicable. The Chinese side is actively implementing the recommendations of the joint study report and is willing to share China's research results on origin-tracing with all parties. What China opposes is politicizing origin-tracing, origin-tracing that goes against the resolution of the World Health Assembly, and reinventing the wheel without proceeding from the first-phase joint study report. Certain countries, including the United States, ignore the facts and accuse China of refusing cooperation on origin-tracing. This is utter confusion of black and white, right and wrong. The United States, instead of China, should be accused of refusing origin-tracing.
