Developing nations at the BRICS summit on Monday brushed away an accusation from President Donald Trump that they are "anti-American," with Brazil's president saying the world does not need an emperor.

President Donald Trump threatened to add a 10% tariff rate on BRICS-aligned countries. The term first applied to 4 countries but the group expanded.

BRICS leaders at a summit on Sunday took aim at US President Donald Trump's "indiscriminate" import tariffs and recent Israeli-US strikes on Iran. Voicing "serious concerns about the rise of unilateral tariff" measures, BRICS members said the tariffs risked hurting the global economy, according to a summit joint statement.
