In 2018, during his first term, Trump imposed tariffs of 30% to 50% on goods imported from China, forcing Beijing to retaliate with its own tariffs against US goods like aluminum, airplanes, cars, pork and soybeans. And we’ve been in a tit-for-tat trade war with China ever since.

Republican presidential candidate Donald Trump warned on Monday that, if elected, he would punish Mexico with tariffs unless the Mexican government moved to stop the flow of fentanyl into the United States.

Trump said he would set a tariff of 25 percent on the country’s largest trading partner if it didn’t close the border, ratcheting up as high as 100 if that didn’t work.
