This law makes it easier for the U.S. to punish Chinese companies and government officials connected to fentanyl production, even if they didn't directly traffic the drug but simply looked the other way while it happened under their watch. It also brings back a requirement (which had lapsed) that the President report to Congress each year on who's been identified as a trafficker and what penalties they've faced. Finally, if a future President declares a national emergency over drug trafficking and wants to use emergency powers to restrict money flows or trade tied to it, this law requires them to first study and publicly explain the likely costs and benefits of doing so, rather than acting immediately without that analysis.
