Donald Trump made a renewed push to impose tariffs(关税) using a range of measures. The president threatened to set duties(关税) of 50% on goods from Canada on August 19th, in retaliation for(作为对……的报复) what America claims are unfair practices by Canadian provinces that don’t buy American products. He was also reportedly ready to impose a new round of levies(征税；征收额) on countries after the 10%-regime expires. And he announced that tariffs of 100% would be introduced for generic drugs(仿制药) from August 2028. Meanwhile, American and Mexican negotiators held another session of bilateral(双边的) trade talks. Mr Trump has refused to extend the US-Mexico-Canada Agreement; America is negotiating with Canada and Mexico separately to seek changes to the pact(协定；条约).
