India, which now faces among the highest tariff rates imposed by the US, called the levy "unjustified and unreasonable".

President Donald Trump announced an additional 25% tariff on India as punishment for importing Russian oil, according to a document posted on the White House website — an escalation of his trade battle with New Delhi and his first use of so-called secondary sanctions on countries the US says are fueling Moscow’s war machine.

US President Donald Trump has increased the tariffs to be imposed on Indian imports to a total of 50%. This comes a day before many of Trump's vaunted tariffs targeting various countries are due to come into effect.
