As the president pursues his goals on Russia and trade, America’s relationship with an important partner in Asia could end up as collateral damage.

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.

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%."
