ABOARD AIR FORCE ONE (Reuters) -U.S. President Donald Trump said on Friday he would consider reducing tariffs on Brazil, under the right circumstances.

Trump was speaking on Air Force One heading to Malaysia for a regional summit. 

Trump increased tariffs on U.S. imports of most Brazilian goods to 50% from 10% in early August, linking the move to what he called a "witch hunt" against the South American country's former President Jair Bolsonaro.

Speaking in Kuala Lumpur, Brazil's current President Luiz Inacio Lula da Silva, known as Lula, said he was optimistic a deal with Trump would be reached. 

"It all depends on the conversation, I work with the optimism that we can find a solution," Lula told journalists.
