Brazil's President Luiz Inacio Lula da Silva said he had a positive meeting on Sunday with his US counterpart President Donald Trump and their respective teams would start "immediately" to discuss tariffs and other matters.

Trump and Lula spoke on the sidelines of the Asean summit in Kuala Lumpur, Malaysia in a meeting to overcome tensions between Brazil and the US after Trump increased tariffs on US imports of most Brazilian goods to 50 percent from 10 percent in early August.

"We agreed that our teams will meet immediately to advance the search for solutions to the tariffs and sanctions against Brazilian authorities," Lula said in a message on X following the meeting.

Trump had linked the tariff move to what he called a "witch hunt" against the South American country's former President Jair Bolsonaro. The US government also put sanctions on a number of Brazilian officials, including Supreme Court Justice Alexandre de Moraes, who oversaw the trial that led to Bolsonaro's conviction for attempting a coup.

Ahead of the meeting on Sunday though, Trump said he could reach some agreements with Lula.

"I think we should be able to make some pretty good deals for both countries," Trump said.

Lula previously described the tariff hike as a "mistake", citing a US$410 billion US trade surplus with Brazil over 15 years.

Brazil's Foreign Minister Mauro Vieira said negotiations will start immediately to work on solutions and a meeting with the US delegation was planned for Sunday.

"We will establish a negotiation schedule and establish the sectors we will talk about so that we can move forward," Vieira told journalists at the summit, adding that Brazil had requested tariffs be suspended during the negotiation process.

It was not immediately clear if the request was agreed to by the US.

"We hope to conclude bilateral negotiations that address each of the sectors of the current American (tariffs on) Brazil in the near future, in a few weeks," Vieira added.

Higher US tariffs on Brazilian goods have begun reshaping the global beef trade, pushing up prices in the United States and encouraging triangulation via third countries such as Mexico, while Brazilian exports to its biggest beef market, China, are booming.

Brazilian beef industry group Abiec said it viewed the meeting between the two leaders as a positive step.

"The understanding between the two countries can preserve the competitiveness of the Brazilian product, guarantee predictability for exporters and expand the presence of (Brazilian) beef in the North American market," it said in a statement. (Reuters)
