The Chicoms maintain Bioweapons programs that would make the U.S three letter agencies jealous. Because unlike the three letters. They don’t need to work under the table and through middlemen. And they have a ready supply of test subjects in the form of political dissidents.

And some of the more Hawkish CCP elements were rather adamant even during Trumps time. Though they were careful to say it without directly saying it. That a War with the U.S wasn’t a question of “If” it was a question of “When.”

And one of the theorized expected first attacks of such a war. Would be unleashing Bioweapons on Civilian population centers behind the lines to both demoralize and disorganize resistance. Hence the presence of illegal and hidden labs in expected belligerent nations wouldn’t be unexpected.

The real question is though. Was it an actual CCP lab? Or an a Front for another group closer to home.
