Zhao Lijian mentioned this hypothesis on Thursday evening and took up the conspiracy theories that are widespread on the Internet.
At the start of the crisis, the director of the Chinese Center for Disease Control and Prevention said that the coronavirus had appeared in a market in downtown Wuhan City.
But in recent weeks, Zhong Nanshan, a Chinese respiratory disease specialist and veteran of the severe acute respiratory syndrome epidemic (SARS, 2002-2003), has raised the possibility that the source of the virus that causes the virus is COVID- 19 is not found in China.
A hypothesis taken up by Beijing.
In his tweet, Zhao Lijian released a video of the director of the United States Centers for Control and Prevention of Disease (CDC), in which he testified before Congress that some Americans who were said to have died of the flu were found they became carriers of the new corona virus.
“The CDC has fallen into a flagrante delicto. When did Patient Zero appear in the US? How many people got infected? "Wrote Zhao.
“The US Army may have brought the epidemic to Wuhan. The United States must be transparent! And you have to publish your data! The United States owes us an explanation, "he said.
Zhao Lijian is not based on a scientific study. On Friday, he only tweeted links to two articles on the Global Research website that are known for spreading conspiracy theses.
According to some theories spread across Chinese social media, the US delegation could have brought the virus to China at the World Military Games, a competition held in Wuhan in October.
The Chinese authorities were accused of hiding the epidemic initially. The Wuhan police reprimanded the doctors who raised the alarm in December.
Although the World Health Organization (WHO) has deliberately chosen a name for COVID-19 disease that is not mentioned in any particular country, Washington often uses terms that refer to the "Chinese" origin of the coronavirus.
US Secretary of State Mike Pompeo called it "the Wuhan virus". An expression that the Chinese Ministry of Foreign Affairs considers "despicable".
More than 130,000 people have been infected with the corona virus, of which almost 5,000 have died.
