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.

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 letters listed a range of tariffs. Goods entering the U.S. from Japan, South Korea, Malaysia, Kazakhstan, and Tunisia will be subject to a 25 percent levy. There will be a 30 percent levy on South African and Bosnian goods, while imports from Indonesia will be subject to a 32 percent rate.

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 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.
