Brazilian President Luiz Inácio Lula da Silva said Thursday that his government has not been successful in trying to negotiate the 50% tariff on Brazilian imports that U.S. President Donald Trump has threatened to impose.

U.S. President Donald Trump's plan to impose a new 50% tariff on all Brazilian products from Aug. 1 could devastate the South American nation's citrus belt, as factories scale back production and orange farmers consider leaving fruit to rot amid a sharp drop in prices.

President Donald Trump’s tariffs on Brazil could push up the cost of orange juice at major American supermarkets like Aldi, Walmart and Wegmans by as much as 25%, according to one US-based orange juice importer.
