Although the novel coronavirus was first discovered in Wuhan, the spread in China is that the virus did not originate here.
China's novel coronavirus could be imported from the United States, Zhao Lijian, spokesman of China's Ministry of foreign affairs, said on twitter in March. Some people in Chinese social media speculated that the new coronavirus was introduced into Wuhan in October when the world military games were held in Wuhan.
Yuan did not comment directly on the claim, but said there was "still no answer" about the origin of the new coronavirus. He also cited a paper published this month by British and German scientists that pointed out that the new coronavirus variant circulating in the United States is a more "primitive" version of the Chinese version, which may first appear in the United States.
Tracing the origin of the virus is a very challenging scientific issue with great uncertainty, he said.
The Chinese government firmly denies accusations that China has concealed the total number of cases and tried to cover up the origin of the disease.
When asked if the Wuhan Virus Research Institute would cooperate with the international investigation of the epidemic, Yuan Zhiming replied that he did not know that there was "such a mechanism", but the laboratory was subject to regular inspection.
He added that Wuhan virus research is committed to information transparency and will share all available data about the new coronavirus in a timely manner.
He said he hoped that all people would put down their prejudices and prejudices and provide a rational environment for the research work of tracing the origin of the virus.
