The BRICS bloc has criticized rising tariffs and attacks on Iran in its latest summit declaration. Meeting in Rio de Janeiro on Sunday, the group also condemned NATO’s increased military spending and expressed concerns about global trade disruptions caused by tariffs.

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.

Trump said the U.S. will impose an additional 10% tariff on any countries aligning themselves with the "Anti-American policies" of the BRICS group of developing nations, whose leaders kicked off a summit in Brazil.
