The Chinese Embassy in Washington also said the report falsely claims Beijing is obstructing a global investigation into the origins of the coronavirus pandemic.
U.S. officials have said the country’s intelligence community does not believe it is possible to resolve the debate over whether the virus emerged from a lab without more information.
Only China can help with the answers to the remaining questions, they added.
President Joe Biden received a classified report earlier this week summarizing the investigation he had ordered.
His summary, which was declassified, said several organizations within the US intelligence community believed COVID-19[feminine[feminine emerged through “natural exposure to an animal infected with this virus or to a closely related progenitor virus”.
However, they had “low confidence” in this conclusion.
A segment of the intelligence community, the summary added, had developed “moderate confidence” that the first human infection with COVID-19 may have been due to a “laboratory-related incident, likely involving experimentation, manipulation of ‘animals or sampling by the Wuhan Institute of Virology’.
This theory was rejected by a team led by the World Health Organization (WHO) who spent four weeks in and around Wuhan in January and February.
Most their report, published in March, has been criticized for not finding sufficient evidence to dismiss the idea – and the WHO director-general has since said there has been a “Premature push” to rule out the theory of laboratory leaks.

The new US report concludes that a “more definitive explanation” will not be possible without new information from China, including clinical samples and epidemiological data on early cases.
“While this review is complete, our efforts to understand the origins of this pandemic will not stop,” Biden said.
“We will do all we can to trace the roots of this epidemic that has caused so much suffering and death around the world, so that we can take all necessary precautions to prevent it from happening again. “
WHO director-general Tedros Adhanom Ghebreyesus said the group was not ruling out any hypotheses.
