Economic tensions between major powers are reaching a new level. The President of the United States, Donald Trump, has issued a direct threat to the member countries of the BRICS alliance, which are seeking to reduce their dependence on the U.S. dollar. In response to these de-dollarization initiatives, he announced 100% tariffs on their exports to the United States. This stance, accompanied by the establishment of a new agency to collect these customs duties, reflects a clear intent to defend the supremacy of the dollar and to counter any challenges to American economic hegemony. As the BRICS explore alternative payment systems, this statement could redefine the power dynamics on the global geopolitical and commercial stage.
