China has a great many reactors, nuclear warheads, acres of low level waste from rare earth processing .. they have as much to hide as the US does, that said there's not a lot to gain here by pretending they don't have potential sources - but isotope fingerprints can be verified and all the byproducts from > 2,000 test explosions and the creation of 10,000+ warheads globally do get mapped and tracked.
