Currently reading a (French) book regarding France-China industrial espionage and relations that was published well before the virus outbreak. Funnily enough, the author describes quite extensively how this P4 in Wuhan came into existence and all the subsequent problems faced by France to get China to honor the deal.

I quote/translate: "In the course of these fifteen years, China has several times failed to live up to their engagement, staying relatively vague about the existence of an offensive biological program. Chinese officials had, for example, previously certified they had no other P4 and no plans to build any, but we now know they do have many, some being quite suspicious, a France official said".

The book is "France-Chine, les liaisons dangereuses" by Antoine Izambard, for those curious.
