The free trade you are referring to is just American hegemony, the Americans spoke, and the rest of the western nations stepped in line.
Almost all western countries made themselves vassals of the Americans, by choice, and then decided to no answer the call of their patron, and also decided at the same time they will do everything possible to disadvantage America while constantly saying how much they hate America.
The whole concept of international law has always just been American benevolence, and the Americans got shit in return. You can suggest the Americans should just eat shit while the rest of the world benefits, but the Americans don't think so, and they won't keep doing it.
