*November 2015 - Italian state-owned media company, ''Rai – Radiotelevisione Italiana'', broadcast a report about Chinese bioterror possibilities back in 2015. The video demonstrated that Chinese scientists and researchers were studying a viral agent similar to coronavirus. They had allegedly derived a SARS-connected virus from mice and bats in order to find out if it could be modified to affect humans. "It is a group of Chinese researchers attaching a protein taken from bats to the SARS virus, Acute Pneumonia, derived from mice. The output is a super coronavirus that could affect man. It remains closed in laboratories and it is only for study purposes, but is it worth the risk – creating such a great threat only for examination purposes?”<ref>https://www.zerohedge.com/geopolitical/chinese-biological-experiments-infect-humans-coronavirus-exposed-2015-italian-state</ref>

*23 February 2017 - ''Nature'' publication raises questions about the BSL-4 laboratory in Wuhan, the Wuhan Institute of Virology asking whether experimentation with deadly viruses was a good idea.

{{quotebox|“BSL-4 is the highest level of bio-containment: its criteria include filtering air and treating water and waste before they leave the laboratory, and stipulating that researchers change clothes and shower before and after using lab facilities. Such labs are often controversial….<br>Future plans include studying the pathogen that causes SARS, which also doesn’t require a BSL-4 lab, before moving on to Ebola and the West African Lassa virus, which do… Worries surround the Chinese lab… The SARS virus has escaped from high-level containment facilities in Beijing multiple times… The plan to expand into a network heightens such concerns. One BSL-4 lab in Harbin is already awaiting accreditation; the next two are expected to be in Beijing and Kunming.”<ref>https://www.nature.com/news/inside-the-chinese-lab-poised-to-study-world-s-most-dangerous-pathogens-1.21487</ref>}}
