Recently two Chinese universities have published research on the origin of the novel Coronavirus that have since been removed from the internet.  According to an article on Cnn.com China is imposing new restrictions on the publication of academic research on the origins of the virus.This new policy requires all academic papers on Covid-19 to undergo extra vetting before publication.  The studies on the origin of the virus and the publication of such studies must be approved by central government officials.  It would seem as if the Chinese government is trying to control the narrative on the origins of the coronavirus pandemic that has claimed more than 100,00 lives and infected 1.7 million people all over the world since it showed up in December in the Chinese city of Wuhan, according to the cnn.com article.  A directive issued by the Ministry of Education's science and technology department lays out layers of approval for academic papers about tracing the origin of the virus. The papers have to be sent through several government organizations for strict vetting and approval before the universities even hear back on whether the papers can be submitted for publication.  Apparently the Chinese government doesn't even want the public to know what the restrictions are or that they are even imposing such restrictions.  A China University of Geoscience in Wuhan posted a notice about the extra vetting on Covid-19 papers on it's website that has since been deleted but luckily a cached version is still availible.  You can read the full article on Cnn.com but basically it looks like the government doesn't want people to know the true origins of the virus.
