Negotiations over future Brazilian steel exports to the United States have been halted since President Donald Trump tweeted earlier this week that he would slap tariffs back on them, the head of Brazil's steel mills body, IABr, said on Thursday.
Trump stunned Brazil and Argentina on Monday, tweeting that U.S. steel and aluminum imports from both countries would be subject to tariffs immediately because both had been "presiding over a massive devaluation of their currencies, which is not good for our farmers."
Marco Polo de Mello Lopes, executive president of Instituto Aco Brasil (IABr), the group that represents Brazilian steel mills, said Trump's decision defied protocol and proper procedure.
