Indeed, a quick look at the subject will turn up dozens of cases of America imposing these restrictions: Canadian lumber, European cheese, Asian and South American shrimp, Canadian wheat, all foreign steel... Then there are all the agricultural and other subsidies: cotton, sugar, corn, the big tax breaks to Boeing (just as Europe gives them to Airbus)...
