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.

The White House justified the move as necessary to “deal with the national emergency” arising from Russia’s war in Ukraine, citing India’s ongoing direct and indirect imports of Russian oil.

US President Donald Trump today signed an executive order imposing an additional 25 per cent tariff on Indian goods, citing New Delhi's continued purchase of Russian oil -- a revenue source the White House says is sustaining Moscow's war in Ukraine.
