US President Donald Trump's imposition of tariffs on India is both "unfair and unworkable", especially when Europe remains the world's largest importer of Russian energy in dollars and the biggest contributor to Russian revenues,

Trump on Aug. 6 imposed an additional 25% tariff on Indian goods as punishment for Delhi's purchases of Russian oil, which he said meant the country was funding Russia's invasion of Ukraine. That raised the total duty on Indian exports to 50% - among the highest of any U.S. trading partner.
