The U.S. government has once again hyped up the issue of COVID-19 origin tracing, and signed the so called COVID-19 Origin Act of 2023 into law in March 2023, making allegation toward China on "laboratory leakage" hypothesis.

　　The trick of ignoring science and fabricating things out of thin air misleads the public and seriously interferes with the work of scientific tracing. The ultimate goal of the U.S. government's sinister move is to politicize and instrumentalize the issue of COVID-19 origin tracing to guide public opinions and smear China.

　　COVID-19 origin tracing is scientific work, which must be carried out through a worldwide investigation and research by experts in relevant fields in a scientific and rigorous manner. In 2021, the WHO released the report on COVID-19 origin tracing joint study with China, which clearly concluded that "laboratory leakage" of the virus was highly impossible, and the conclusion has received wide support from the international scientific community.

　　American politicians have attacked China for its lack of information transparency and obstructing investigations into the origin of the virus. But the reality is that as of now, China has shared the most data and research results on COVID-19 origin tracing.

　　China is the only country that invited international experts from the WHO to cooperate in tracing the origin of the virus more than once, and the only country that has repeatedly organized its experts to share their progress on COVID-19 origin tracing with the WHO advisory group.

　　In contrast, the U.S. has refused to respond to any calls for investigations into its laboratories or provide data on early suspected cases. Washington should have conducted honest and close cooperation with other countries, including China. Instead, it has taken the issue of COVID-19 origin tracing as one of the means to contain China. While closing its door to international investigation, the U.S. is making groundless accusations against China on the issue.

　　Scientists have long noted that tracing the origin of any virus has historically required long-term, extensive sample collection that could take years or even decades. U.S. politicians' constant rushing to make a conclusion on the COVID-19 origin through an unwarranted charge will only further damage the country's international credibility and image.

　　The U.S. should immediately stop political manipulation to COVID-19 origin tracing, respond to the legitimate concerns of the international community as soon as possible, and share its data of early suspected cases with the WHO.
