The meeting, which was held digitally, had been convened by the Brazilian president to discuss Trump's trade policy and mobilize support for multilateralism.
Using tariffs as blackmail to achieve market dominance and influence domestic politics is becoming increasingly normalized, said Lula during the meeting.
In August, US President Donald Trump made good on his previous threats against Brazil and introduced 50-percent tariffs on goods from the country.
Trump has, among other things, motivated the tariffs with the Brics cooperation and Brazil's energy trade with Russia. Another factor is the ongoing legal process against the country's former president Jair Bolsonaro – a process that the American president has described as a "witch hunt".
Among the participants at Monday's Brics meeting were Russian President Vladimir Putin, South African President Cyril Ramaphosa – and China's leader Xi Jinping, who urged countries to "resist all forms of protectionism".
The Brics cooperation was founded by Brazil, Russia, India, China, South Africa, but the cooperation now includes more countries, including the United Arab Emirates, Egypt, Ethiopia, and Iran.
