<h1>Tariff-based sanctions to pressure buyers of Russian energy aim to compel negotiation with presidential waivers subject to congressional review.</h1> A bipartisan bill would impose tariff-based sanctions on countries importing Russian energy and strategic exports to deprive Russia of war revenue and compel negotiation. The legislation allows the president to grant limited waivers, subject to renewal, but preserves congressional review and a mechanism to overturn waivers requiring a Senate supermajority. Sponsors describe the measure as a strategic shift from existing sanctions, emphasise continued bipartisan support, and note ongoing negotiations with the administration over waiver authority ahead of a hoped-for pre-recess vote.
