My question is: or what?

If someone was to defy this order, what's Donald Trump going to do about it? As far as I can tell, there's no mention of sanction of any kind in the order itself. So, like what happens if I transact with Byte Dance?

Will he send his goons around to throw me in an unmarked van, maybe?

He's upset that China is the only adversary of the US not backing him.

Russia and the Saudis are actively trying to force the election to him, China is trying to stop that.

None are our friends.

Oh and Activision Blizzard just voted NO on executive compensation.
