<h1>President threatens 10% tariffs on Brazil Russia India China South Africa over dollar challenge</h1> The US President threatened to impose 10 percent tariffs on member nations of the economic bloc comprising Brazil, Russia, India, China, and South Africa, claiming the group seeks to undermine dollar dominance. The President described the alliance as a 'little group' that is 'fading out fast' and warned that any attempt to challenge the dollar's status as the world's reserve currency would face immediate tariff retaliation. This marks the second such threat within ten days. The President emphasized that losing the dollar's reserve currency status would be equivalent to 'losing a world war' and stated that member countries are 'virtually afraid' of potential consequences. The economic bloc recently expanded to include additional nations and held its summit in Brazil, where members criticized unilateral tariff measures as inconsistent with international trade rules. Meanwhile, bilateral trade negotiations between the US and one member nation concluded their fifth round of discussions.
