<h1>Russian leader warns U.S. 'colonial-era' pressure on major economies risks trade retaliation, WTO disputes and strained ties</h1> A Russian president publicly criticized a U.S. president for applying 'colonial-era' pressure on leaders of major economies, noting those countries' domestic political constraints and historical sensitivities, and warned such tactics could affect bilateral relations. The U.S. measures cited include a 50% tariff on purchases of Russian oil by India and an earlier 145% tariff on China that was later reduced to 30% under an interim deal (with reciprocal Chinese tariff reductions). The exchange highlights possible trade-law and diplomatic risks, including WTO issues, retaliatory tariffs and strain on multilateral and bilateral negotiations.
