The 50% tariffs announced by US President Donald Trump on many Brazilian products took effect Wednesday, a situation that China is already taking advantage of by opening its market to Brazilian coffee, one of the products most affected by the trade measures.

As U.S. tariffs on Brazilian goods jumped to 50% on Wednesday, Brazil's President Luiz Inacio Lula da Silva told Reuters in an interview that he saw no room for direct talks now with U.S. President Donald Trump that would likely be a "humiliation.

The president typically ties his tariffs to trade policy, but he hit Brazilian products with the highest rate of any country's goods largely due to politics.
