The U.S. State Department summoned China’s ambassador to the United States on March 13 after a top Beijing official suggested that the U.S. military might be responsible for introducing the deadly coronavirus to Wuhan, ground zero of the pandemic.
The meeting came after a vice director at China’s foreign ministry Zhao Lijian, in a series of posts on Twitter—a platform inaccessible in China—accused the United States of not being transparent about what it knows about the disease, while pushing an unfounded conspiracy theory that the outbreak originated in the United States.
