Zhao, one of the country’s most notoriously hawkish diplomats, referenced a U.S. military location that has been baselessly linked to the coronavirus outbreak by Chinese media. Describing Fort Detrick in Frederick, Md., as “full of suspicion,” Zhao said the United States needed to open it up to international scrutiny. “There are more than 200 U.S. biological laboratories scattered around the world. How many secrets are there?” he said. Fort Detrick hosts elements of the country’s biological defense program. While trying to deflect criticism of their handling of the coronavirus outbreak, Chinese officials have repeatedly responded by calling for the U.S. base to be opened to international inspectors.
