China is certainly lax, but the US doesn't allow autonomous ATTACK systems. For Attack systems it is always required that a human makes the judgement call when to attack.
Or least it didn't until the current regime.
The US does have autonomous defensive systems.
I could be wrong though, can you post your evidence? The closest I could find is loitering munitions.
Even so, a company shouldn't be forced to go against its ethics if those ethics help humans.
