President Luiz Inácio Lula da Silva (PT) said he intends to speak by phone with U.S. President Donald Trump to address diplomatic strains.

The potential conversation follows a series of economic and political clashes that threaten the stability of trade and diplomatic relations between the two largest economies in the Americas.

Speaking in Rio de Janeiro on July 17, Lula said he wants a "war of truth" against the U.S. leader [1, 2]. The tensions escalated after the U.S. imposed a 25% tariff on various Brazilian export products [3], which took effect on July 22, 2026 [4].

Lula said, "When Trump speaks, I will speak. Against Brazil, no one wins by lying" [2].

Beyond the trade dispute, the two nations are clashing over the Pix payment system, and controversies regarding labor norms [5]. The diplomatic rift has also manifested in the suspension of the visa for Ambassador Maria Luíza Viotte [5].

Lula said the disputes are tied to broader concerns regarding U.S. interference in the internal politics of Brazil [5]. The Brazilian leader signaled that a direct conversation is necessary to resolve these multifaceted disagreements.

"I want a war of truth against the US leader Donald Trump," Lula said [1].

"When Trump speaks, I will speak. Against Brazil, no one wins by lying."

The friction between Brazil and the U.S. represents a shift from traditional diplomatic engagement to a more confrontational posture. By framing the dispute as a 'war of truth,' Lula is attempting to pivot from a defensive economic position—caused by the 25% tariffs—to a political narrative of national sovereignty. The inclusion of the Pix payment system and ambassadorial visa issues suggests the conflict is not merely about trade, but about the fundamental alignment of their respective financial and political systems.
