Donald Trump declared Russia an "extraordinary threat" to the United States on Wednesday, as he announced his first sanctions due to Vladimir Putin's refusal to stop the war in Ukraine.
The US president said he would hit India with an additional 25 percent trade tariff on the purchase of Russian oil, an important source of revenue for the Kremlin.
The so-called secondary tariff, which brings the total tax against India to 50 percent, was announced in an executive order signed hours after envoy Steve Witkoff, Trump's top envoy, met with Vladimir Putin in the Kremlin for confrontation talks.
Trump gave Putin until Friday to agree to a ceasefire or face tariffs on Russia's main trading partners.
"I have received additional information from various senior officials, among other things, on the actions of the government of the Russian Federation regarding the situation in Ukraine," Trump said after the meeting with Witkoff.
The US president said this information meant that Moscow poses "an unusual and extraordinary threat to the national security and foreign policy of the United States".
The language is a significant change in tone from earlier this year, when Trump did his best to appease Putin in order to convince him to sit at the negotiating table.
"I determine that it is necessary and appropriate to impose an additional ad valori tax on imports of articles of India, which directly or indirectly imports oil of the Russian Federation," Trump added.
Trump had suggested that Witkoff's meeting with Putin would determine any decision for the US president to implement threats to impose tariffs on countries that buy Russian energy.
