Countries supporting the “Anti-American policies” of the BRICS alliance will face an additional 10 percent tariff, US President Donald Trump has announced.

“Any Country aligning themselves with the Anti-American policies of BRICS, will be charged an ADDITIONAL 10% Tariff. There will be no exceptions to this policy. Thank you for your attention to this matter!,” Trump wrote on Truth Social.

The US president, however, did not elaborate on what he meant by the “Anti-American policies” of the BRICS.

The BRICS group initially included Brazil, Russia, India, and China; their leaders first met in 2009. South Africa later joined the alliance, and last year Egypt, Ethiopia, Indonesia, Iran, Saudi Arabia, and the United Arab Emirates joined.
