The U.S. president has threatened a 10 percent tariff on any country aligned with the BRICS bloc, a potential blow to Russia.

President Trump and Congress are threatening harsh sanctions against Moscow for its three-year war in Ukraine.

Donald Trump says he plans to increase blanket tariffs to 15 or 20 per cent on goods imported by the United States' trading partners. But it appears 'tariff fatigue' is setting in as the Australian dollar and share market largely ignore the US President's latest remarks.

U.S. President Donald Trump on Sunday threatened to impose additional tariffs on any group linked with the BRICS intergovernmental organization after the group expressed "serious concerns" about him unilaterally imposing tariffs.

President Trump threatened an additional 10% tariff on imports from countries aligning with BRICS. BRICS, originally Brazil, Russia, India, and China, was used to describe emerging economies.

Russia has said BRICS is not anti-American, rejecting Trump’s threats as “language of manipulation and coercion.” Russian Deputy Foreign Minister Sergei Ryabkov has dismissed suggestions that the BRICS group of emerging economies is anti-American, responding to recent remarks by US President Donald Trump.

President Donald Trump has voiced sharp frustration with Russian President Vladimir Putin over the ongoing war in Ukraine. In a candid White House meeting, Trump accused Putin of causing massive loss of life and hinted at possible new sanctions against Moscow.

Russia launched another major attack on Ukraine overnight, officials said. The airstrike is the latest escalation in the more than three-year war, and came after President Trump said the U.S. will resume sending weapons to Ukraine following a brief pause.
