Brazilian President Luiz Inacio Lula da Silva said he wanted to find a diplomatic solution to U.S. President Donald Trump’s threat of 50% tariffs on Brazilian exports, but vowed to reciprocate like-for-like if they take effect on August 1, BBC reported.

"We'll first try to negotiate, but if there's no negotiation, the law of reciprocity will be put into practice," Lula said in an interview with Record TV, citing a law Congress recently passed giving the president powers to retaliate against trade barriers. "If they're going to charge us 50, we'll charge them 50."

The president is unlikely to announce any retaliatory measures until the tariffs are implemented, said a Brazilian diplomat who requested anonymity to describe internal government debates. "We have until August 1," the source said, according to BBC.

In a letter to Lula published on Wednesday, Trump linked the tariffs to Brazil's judiciary launching legal proceedings against former President Jair Bolsonaro, who is on trial on charges of plotting a coup to stop Lula from taking office in 2023 after hundreds of pro-Bolsonaro supporters stormed Congress. Trump said Bolsonaro was the victim of a "witch hunt."
