I personally think this was an accidental release of their bioweapons experiment
BUT..there are those that think China is perfectly capable of intentionally releasing it with no thought to how it would kill their own people in hopes of world domination.
So , in theory, China could release another version.
I saw where they escaped scientist said this is a bioweapon but havent read up on what that scientist said.
The answer to your question may be the same as, does China have TDS?
