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

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.

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

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.

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.

The Russian leader is convinced that Moscow’s battlefield superiority is growing, and that Ukraine’s defenses may collapse in the coming months, according to people close to the Kremlin.

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.
