I remembered a couple of years ago someone passed to me a letter to sign demanding national governments to protest against the development of a group of BSL-4 labs in China. (The authors were concerned about safety standards. For me it was about animal welfare - obvsly, in China all psychos an idiots can do whatever they want and call it "research".)
I googled an old article about it in Nature (now there's a diplomatic note attached at the top):

A laboratory in Wuhan is on the cusp of being cleared to work with the world’s most dangerous pathogens. The move is part of a plan to build between five and seven biosafety level-4 (BSL-4) labs across the Chinese mainland by 2025, and has generated much excitement, as well as some concerns.
This puts things in a new perspective. The risk of pandemic outbreaks can't be shrugged off as that of a rare event. With 7 such labs in China it is a quantifiable probability and should be modelled. Don't you think?
