The reimposition of Trump's higher tariffs, and also retaliatory measures from U.S. trading partners who did not reach a deal in time, threatens to pull global trade back to where it was in April, with widespread disruption, market volatility and looming economic pain.

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.

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.
