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.

U.S. President Donald Trump warned early Monday that countries that support of BRICS nations -- Brazil, Russia, India and China -- would be slapped with an additional 10% tariff when across-the-board

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.
