"We want to build a Latin American doctrine, with Latin American teachers and students, so that we can dream of an independent continent, one where no president from another country will ever again dare to speak arrogantly to Brazil, because we will not accept it," Lula said during an event with high school students in Sao Bernardo do Campo municipality.

Regarding the defense of sovereignty, Lula said it is not a matter of courage but a matter of "dignity and character", Xinhua reported.

The remarks came as Brazil and the United States began thawing relations following the tariffs of up to 50 percent imposed by Washington on Brazilian goods since early August.

Lula said Wednesday that Brazil and the United States would hold a formal bilateral meeting to discuss the additional tariffs, following his virtual conversation earlier this month with U.S. President Donald Trump.
