Trump declared on Truth Social: “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 did not elaborate on what he meant by “anti-American policies.”

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.

Leaders of the BRICS group of emerging economies meeting for their annual summit had hoped to downplay any differences with the U.S. But even a toned down group proclamation drew the ire of President Trump.
