In February 2020, as the COVID-19 outbreak was spreading through Wuhan, Chinese state media and scientific publications identified Tong Xiao (童骁) as a deputy director of the Wuhan National Biosafety Laboratory, commonly known as the Wuhan P4 laboratory.
Tong’s name appeared in two related accounts published before and during the outbreak. Taken together, the reports provide a relatively detailed record of his professional background, his role in the construction of the P4 facility, and his position at the Wuhan Institute of Virology when the COVID-19 outbreak began.
This article removes the political and promotional language from those accounts and focuses on the underlying facts.
From USTC to the Wuhan Institute of Virology
Tong Xiao was born in September 1969 and graduated from the University of Science and Technology of China (USTC) in 1993 with a bachelor’s degree.
According to a 2016 profile published through the Chinese Academy of Sciences, Tong joined the Wuhan Institute of Virology (WIV) after graduation and remained there throughout his career.
His recorded positions included:
1994: Research Intern
1998: Assistant Researcher
2000: Master’s degree
2003 onward: Doctoral studies while working
The 2016 profile states that Tong’s early research focused primarily on microorganisms and their metabolites. From approximately 2002 onward, his work shifted toward molecular virology, with HIV identified as his principal research direction at the time of the profile.
The same source states that he participated in research associated with several Chinese national scientific programs, including the National Key Technologies R&D Program, the 973 Program, and the 863 Program.
These details place Tong within the Wuhan Institute of Virology’s research system for more than two decades before the COVID-19 outbreak.
His role in constructing the Wuhan P4 laboratory
Tong’s connection with the Wuhan P4 laboratory was not limited to being a researcher working inside the completed facility.
According to a 2016 Chinese Academy of Sciences profile, during the construction of the laboratory he served as the technical lead for the project construction organization and the chief on-site project coordinator.
His responsibilities included:
organizing and making decisions concerning construction-site operations;
technical review of equipment procurement;
technical approval of equipment installation;
coordinating construction work;
addressing technical changes during construction;
coordinating the requirements of the French design team with Chinese construction standards; and
assisting in the selection of suppliers for equipment used in the laboratory.
The profile states that construction was completed at the end of 2014, that equipment commissioning was completed during 2015, and that third-party testing by Chinese and French testing organizations was completed in March 2016.
The facility subsequently underwent an accreditation-related inspection in April 2016.
The construction history is significant because it establishes Tong as someone involved in the laboratory before it became operational, rather than someone appointed to an administrative position only after its completion.
Deputy director of the Wuhan P4 laboratory
By February 2020, Tong was publicly identified as Deputy Director of the Wuhan National Biosafety Laboratory.
The laboratory is the P4/BSL-4 facility operated by the Wuhan Institute of Virology.
A February 11, 2020 report in China Science Daily identified Tong as one of the people involved in the laboratory’s response to the COVID-19 outbreak.
The report stated that the P4 laboratory was undertaking several categories of work, including:
drug screening and evaluation;
animal infection models;
vaccine research and development; and
virus tracing.
Tong was quoted describing the laboratory’s work as a race against the virus and explaining that different departments were required to support one another to keep the facility operating.
Those statements are important because they establish his institutional position and the categories of work publicly associated with the P4 laboratory during the early phase of the outbreak.
They do not, by themselves, establish that Tong personally conducted every experiment described in the article. His documented position was that of deputy director, and the article described work being conducted by the laboratory as an institution.
The P4 facility and high-containment work
The February 2020 report also described work being performed inside the laboratory by other members of the research and support staff.
For example, senior laboratory technician Zhang Huajun (张化俊) was reported to have been working on the large-scale cultivation of virus for research related to an inactivated vaccine.
The report also described animal infection-model experiments involving mice and monkeys, as well as testing of antibodies from patients who had recovered from the disease.
Other laboratory personnel were responsible for biosafety management and protective-equipment testing.
The description provides some indication of the range of activities taking place within the P4 laboratory during the early outbreak. It should nevertheless be distinguished from Tong’s individual research record.
Tong’s research background
The available profile describes Tong’s scientific specialization primarily in terms of molecular virology and HIV research.
This is a relevant distinction when examining his role during the COVID-19 outbreak.
The public record cited here establishes that:
Tong had worked at the Wuhan Institute of Virology since the 1990s.
His research had shifted toward molecular virology.
HIV was identified as his main research direction in the 2016 profile.
He had participated in several Chinese national research programs.
He had played a technical and organizational role in construction of the Wuhan P4 laboratory.
By February 2020, he was serving as the laboratory’s deputy director.
The record does not establish, from these sources alone, that Tong was the principal scientist responsible for the laboratory’s coronavirus research, nor does it establish personal involvement in any particular experiment.
That distinction matters when reconstructing institutional responsibility.
Why Tong’s position is relevant to the history of the Wuhan P4 laboratory
Tong’s career provides an unusual continuity between the construction, operation, and COVID-19-era activities of the Wuhan P4 laboratory.
He was involved in the construction project before the facility opened. Four years later, he was publicly identified as one of its senior managers.
In other words, the available public record connects the same individual to three stages of the facility’s history:
construction → commissioning and accreditation → operation during the COVID-19 outbreak.
This does not establish the origin of SARS-CoV-2, nor does it establish that the laboratory caused the outbreak. Those are separate questions requiring separate evidence.
What it does establish is a documented institutional role.
For researchers examining the history and organizational structure of the Wuhan Institute of Virology, Tong Xiao is therefore a relevant figure to track through Chinese scientific and government records.
Sources
The principal source for Tong’s background and his role in construction of the P4 laboratory is a 2016 Chinese Academy of Sciences profile reproduced by the University of Science and Technology of China New Alumni Foundation.
A second source is the February 11, 2020 report published by China Science Daily, titled:
“Racing Against the Virus, Protecting Lives — A Close Look at the Front Line of the Chinese Academy of Sciences Wuhan Institute of Virology in the Fight Against the Epidemic.”
The latter identified Tong Xiao as a USTC alumnus and as Deputy Director of the Wuhan P4 Laboratory, while describing the laboratory’s activities during the early COVID-19 outbreak.
For an evidence-based reconstruction, the original Chinese publications should be preserved alongside any English translation, particularly where official institutional titles and project responsibilities are concerned.
Tong Xiao’s Party Membership and Project Role
A separate profile published by the Chinese Academy of Sciences (CAS) on July 20, 2016 provides additional information about Tong Xiao’s institutional position and political affiliation at the time.
The CAS profile states that Tong Xiao was born in September 1969 and joined the Chinese Communist Party (CCP) in July 2000. At the time of publication, he was identified as Deputy Director of the Project Office of the Wuhan National Biosafety Laboratory, the facility commonly known as the Wuhan P4 laboratory.
The article was published under a CAS feature on “Outstanding Communist Party Members.” Much of the original text consists of political and ideological assessments of Tong’s adherence to CCP doctrine, including references to communist ideals, following the Central Committee, and promoting CCP policies. Those passages are not relevant to establishing his technical responsibilities and are therefore omitted here.
What is more significant for the institutional record is the description of Tong’s role in the construction of the laboratory.
Technical responsibility for the P4 project
According to the CAS profile, Tong served as the technical lead for the project construction organization and the chief on-site project coordinator during construction of the Wuhan P4 laboratory.
The description attributes several specific responsibilities to him:
making organizational and technical decisions at the construction site;
reviewing and approving technical aspects of equipment procurement;
reviewing and approving equipment installation;
dealing with construction and engineering problems;
coordinating French design requirements with Chinese construction standards;
selecting qualified suppliers for what the article described as China’s first P4 laboratory; and
making decisions concerning technical changes to the project.
The profile states that the construction project took approximately four years.
According to the chronology given by CAS, construction was completed by the end of 2014, individual-unit and integrated equipment commissioning was completed by the end of 2015, and testing by third-party organizations from both China and France was completed in March 2016. In April 2016, an expert group from the relevant Chinese accreditation authority conducted an on-site inspection.
This places Tong in a technically significant position during the transition of the facility from a construction project to an operational high-containment laboratory.
Interaction with French designers and contractors
The CAS account also gives a more concrete picture of the international engineering work involved in constructing the facility.
Tong’s project team worked with:
a French design team;
a Chinese design team;
construction contractors;
Chinese and French supervision organizations.
The article specifically mentions his involvement in discussions with French designers concerning the installation and selection criteria for sealed valves, as well as the fabrication and design drawings for a double-layer wastewater pipeline system.
The profile states that during the 2014 Spring Festival, Tong continued communicating with the French designers because the time difference meant that some of the technical discussions had to take place at night.
These details are useful because they describe his position in terms of concrete engineering responsibilities rather than simply giving him a general managerial title.
Procurement, suppliers and cost control
The CAS profile also connects Tong’s position with procurement and supplier management.
It states that his responsibilities included identifying qualified suppliers for the P4 project and making technical decisions concerning equipment and construction changes. The article further says that the project management structure sought to control project progress, quality and costs, and that Tong maintained professional distance from construction companies and suppliers.
The original article presents these points as evidence of Tong’s integrity and political discipline. For an institutional investigation, however, the more relevant fact is that the official account places him at the intersection of technical decision-making, procurement, construction management and project administration during the creation of the Wuhan P4 laboratory.
That is a more concrete description of his role than simply calling him a laboratory researcher.
A ten-person project team
The CAS profile states that Tong led a ten-person construction team during the project.
It describes the team as having members with different educational and professional backgrounds and says that Tong was responsible for coordinating their work and allocating resources.
Again, the original article surrounds this information with extensive political language concerning selflessness, Party ideals and exemplary Communist Party membership. The underlying organizational fact is simpler: Tong was described by CAS as the leader of a ten-person project team responsible for supporting the construction and subsequent operation of the P4 facility.
CCP membership was part of the official profile
Tong’s CCP membership is not inferred from his position or from secondary reporting. It was explicitly stated by the Chinese Academy of Sciences.
The July 20, 2016 CAS profile records:
Tong Xiao — born September 1969; joined the Chinese Communist Party in July 2000.
The same official profile was published specifically as an entry in a CAS feature on Outstanding Communist Party Members.
This is relevant when reconstructing the institutional background of senior personnel at the Wuhan P4 laboratory. It shows that Tong’s political affiliation was itself considered relevant enough by his institution to be included in his official professional profile.
What the document establishes
Taken together with the other public material on Tong Xiao, the 2016 CAS profile establishes the following points:
Tong Xiao joined the Wuhan Institute of Virology after graduating from the University of Science and Technology of China in 1993 and remained there throughout his career.
He joined the CCP in July 2000.
During construction of the Wuhan P4 laboratory, he was described as the technical lead for the project construction organization and chief on-site project coordinator.
His responsibilities included construction-site decisions, technical review of equipment procurement and installation, supplier selection and technical changes.
He worked with Chinese and French design, construction and supervision teams.
He led a ten-person project team.
By July 2016, he was identified by CAS as Deputy Director of the Project Office of the Wuhan National Biosafety Laboratory.
This record is particularly useful because it documents Tong’s involvement before the P4 laboratory entered routine operation. It therefore provides a direct institutional link between the construction of the facility and his later position within it.
The CAS article should also be read for what it is: an official profile produced as part of a CCP-themed campaign. Its descriptions of Tong’s political qualities are promotional and should not be treated as independent assessments. The concrete job titles, dates, project chronology and responsibilities, however, can be separated from that promotional material and examined as documentary evidence.
