There is no reasoning about this. Government as an entity (especially the "Rainbow" West ones like the EU and US) is literally schizophrenic or crazy or has multiple personality disorder (that's the best analogy I can come up with). Their laws are not internally consistent, their words don't match their actions, they entertain conflicting and opposing priorities, they actively do things to their own detriment, they promote the well-being of everyone but their own citizens, they can't get consensus on anything from their own populace, and they blame everyone and themselves too at the same time for their own failings.

They admit their own failings by showing us who they are "allergic" to. So yes, China may be a "bad guy", but they're painted as a boogeyman for a reason.
