<h1>Senior US lawmaker warns 50% tariffs, including 25% on Russian oil, threaten US-India relationship and cooperation</h1> A senior US lawmaker warned that the US President's imposition of tariffs on India-totaling 50%, including a 25% levy on purchases of Russian oil-risk undermines the bilateral relationship and urged congressional support for deeper ties. The lawmaker met with the Indian ambassador, reaffirming commitments on cooperation and expressing concern about the tariffs' arbitrary nature. The ambassador engaged with multiple US legislators to discuss trade, energy security, and the Indo-Pacific, defending India's energy purchases as driven by national interest and market dynamics and seeking continued dialogue amid strained relations caused by the tariffs.
