US imposes sweeping Russia sanctions: 100% tariffs on energy buyers, 500% on imports

The US has authorized sweeping new sanctions targeting Russia, including tariffs of up to 100% on major buyers of Russian energy and 500% duties on imports from Russia. This escalates economic pressure on Moscow and its trading partners, potentially reshaping global energy and trade flows. The move signals a significant hardening of US policy, though implementation and third-country compliance remain uncertain.
