The below article is from World renowned NATURE Magazine dated back to 2015 which VERY CLEARLY says Dr.Ralph Baric & Shi Zengli's team CREATED a Novel SARS - Like Virus.
Creation of Chimeric Novel SARS- like VIRUS
The article says :
Therefore, to examine the emergence potential (that is, the potential to infect humans) of circulating bat CoVs, we built a chimeric virus encoding a novel, zoonotic CoV spike protein—from the RsSHC014-CoV sequence that was isolated from Chinese horseshoe bats1—in the context of the SARS-CoV mouse-adapted backbone.
{ What is a Chimeric Virus -
A chimera virus is defined by the Center for Veterinary Biologics (part of the U.S. Department of Agriculture's Animal and Plant Health Inspection Service) as a "new hybrid microorganism created by joining nucleic acid fragments from two or more different microorganisms in which each of at least two of the fragments contain essential genes necessary for replication."[1] The term chimera already referred to an individual organism whose body contained cell populations from different zygotes or an organism that developed from portions of different embryos. In mythology, a chimera is a creature such as a hippogriff or a gryphon formed from parts of different animals, thus the name for these viruses.
}
The hybrid virus allowed us to evaluate the ability of the novel spike protein to cause disease independently of other necessary adaptive mutations in its natural backbone. Using this approach, we characterized CoV infection mediated by the SHC014 spike protein in primary human airway cells and in vivo, and tested the efficacy of available immune therapeutics against SHC014-CoV.

So the Chimeric Novel SARS like virus was created back in 2015 by a team having both US & Chinese Virologist.
DOES CHIMERIC VIRUS CAN BE USED AS BIO WEAPON ?
- Combining two pathogenic viruses increases the lethality of the new virus[3] which is why there have been cases where chimeric viruses have been considered for use as a bioweapon. For example, the Soviet Union's Chimera Project attempted to combine DNA from Venezuelan equine encephalitis, smallpox and Ebola virus in the late 1980s[4]. A combination smallpox and monkeypox virus has also been studied ( AS PER WIKIPEDIA )
KIND NOTE :
These are very tough times.
The COVID19 Pandemic has created lot of economical hazards all over the world.
