- China allowed WHO experts to visit all places they wanted to go and meet all people they wanted to see.
- The results of the WHO-China joint study are able to stand the test of time.
- WHO plan to focus on "lab leak" shows disrespect to common sense and arrogance to science.
- China cannot accept the current version of the second phase investigation into the origins of the COVID-19 virus launched by the World Health Organization, for the plan has been compromised by political manipulation and disrespect of scientific facts.
Zeng said the plan has listed the hypothesis of China had violated lab regulations and leaked the virus as one of the major research objectives, and he was "very shocked" after reading the proposal.
"We hope the WHO can carefully consider the advice by Chinese scientists, take investigating the origin of the COVID-19 virus as a scientific question free from political interference, and proactively and properly conduct sustained investigations into the origin of the virus in various countries across the world," he said.
- Origin tracing efforts should be carried out more extensively across the world to search for early cases, to carry out molecular epidemiology study and identify animal reservoirs and intermediate hosts.
- Not a single leak incident has occurred at the Wuhan P4 lab since it started operation in 2018.
The institute had not come in contact, stored or researched the virus before Dec 30, 2019.
The infrastructure, management, team composition and working protocols at the institute's P4 biosafety laboratory are the same as other P4 labs in operation. Since the laboratory began operating in 2018.
Yuan said the laboratory has stable and reliable biosafety precautions in place, and has established a set of complete biosafety management systems and a professional team to bolster, manage and maintain its operation.
Refuting the allegation that three workers at the institute were infected with the disease in November 2019, Yuan said people propagating the claim were never able to provide names of the alleged researchers. "The claim has been created out of thin air," he said.
He said unfounded accusations that implicate the institute as the source of the outbreak has disturbed the institute's scientific research work and disrupted international communication and cooperation.
Earlier this year, Chinese and international experts visited Wuhan to study the origin of the virus, which was organized by the World Health Organization.
The team had conducted field visits at the institute, and in particular, learned about the institute's implementation of management and safety regulations, as well as its past and current research projects.
The mission had reached the conclusion that it is extremely unlikely that the virus originated from a laboratory, he said.
Chinese researchers suggested that more probe should be directed to countries where P4 laboratories had not been visited by international experts, reviewing possible safety risks and laboratory incidents there, Liang said.
- Study on the origin of COVID-19 virus on animals should be the focus of next phase and it should be carried out in countries and regions with bat distribution.
- China did not hide the original data and it's international custom to protect privacy of patients.
China had shared clinical data of early COVID-19 patients, information from epidemiological surveys, and lab test results with the expert team for joint study and analysis, and the findings were later published in the WHO report.
However, Liang said these data contained personal information and it is against relevant laws and regulations in China to allow the data to be taken to other countries.
China has not purposefully withhold data from the research team, and the credibility of the conclusions from the joint report is not undermined simply because China wants to protect its citizen's privacy by not allowing experts to take their personal data with them to other countries.
