<h1>US senators advance bipartisan bill imposing 500% tariffs on countries buying Russian energy exports</h1> US senators from both parties are advancing legislation imposing 500% tariffs on goods from countries purchasing Russian energy exports, primarily targeting China and India which comprise 70% of Russia's energy trade. The bipartisan bill aims to pressure Russia toward Ukraine negotiations by targeting its customer base rather than direct sanctions. Senators briefed European allies and Ukraine officials in Rome, seeking to pass the measure before August recess. The legislation faces White House concerns over presidential waiver authority, with the administration wanting full control over lifting penalties without congressional oversight. Congressional leaders express optimism about bipartisan support while acknowledging ongoing negotiations with the White House on final terms.
