President Donald Trump imposed 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.

Tariffs on Indian exports to the United States will surge to 50 percent by late August, as part of an effort by President Trump to pressure Russia into resolving its war in Ukraine.

In an executive order, Trump says "I find that the Government of India is currently directly or indirectly importing Russian Federation oil" and due to those purchases, imports of Indian goods into the United States "shall be subject to an additional ... rate of duty of 25%."
