<h1>Former security officials and lawmaker say US tariffs on Russian oil harm US-India ties, boost China-Russia alignment</h1> A US lawmaker and former national security officials warn that the US president's imposition of steep tariffs and secondary duties on purchases of Russian oil is undermining a three-decade bipartisan strategic partnership with India, harming bilateral trade and pushing India toward closer ties with China and Russia. They allege the measures exceed duties on other partners, damage exports in key sectors, and reflect personal or transactional motives tied to dealings with Pakistan. Former officials say the conduct inflicts significant strategic harm to US interests and will require substantial effort to repair diplomatic and security relationships.
