Trump has threatened to impose 100% tariffs against the bloc if they take any moves to undermine the dollar. Last year, at the summit hosted by Russia in Kazan, the Kremlin sought to develop alternatives to U.S.-dominated payment systems which would allow it to dodge Western sanctions imposed after Russia’s invasion of Ukraine in February 2022

President Donald 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 on Sunday.

"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!

BRICS leaders are meeting in Brazil for a two-day summit. But China's Xi Jinping and Russia's Vladimir Putin are skipping the gathering.
