In responding to a recent article on the White House website titled "Lab Leak: The True Origins of COVID-19," the spokesperson of the National Health Commission stated that like previous U.S. allegations of  "Wuhan lab leak," the so-called rationale of the article completely lacks scientific basis, and the "evidence" is entirely fabricated. The U.S.'s repeated attempts to blame and smear China on the issue of the origins of SARS-CoV-2 only expose its malicious intent to politicize scientific issues, a practice long dismissed by the international scientific community. Its agenda to use the pandemic as a tool to contain China is doomed to fail. As growing information and evidence show that SARS-CoV-2 emerged in the U.S. at an even earlier date, the next phase of origin-tracing should be conducted in the U.S. We urge the U.S. to immediately cease its baseless accusations and smear campaign against China, be accountable for its own problem, and provide a credible, responsible explanation to the international community and people worldwide.
