Washington, Nov 7 (PTI) US President Donald Trump used tariffs as a diplomatic tool to "buy justice" and had urged India to “stop buying oil” from Russia to help end the Ukraine war, Commerce Secretary Howard Lutnick has claimed.

Lutnick made the remarks in an interview with Fox News on Thursday, defending Trump’s use of tariff powers as the Supreme Court heard arguments on its legality.

The court is examining whether it was lawful for Trump to use emergency powers under the 1977 International Emergency Economic Powers Act (IEEPA) to impose sweeping reciprocal tariffs on several countries, including India.

"The president is using these taxes to buy justice; he is using the tariffs to end the war in Russia and Ukraine, where he has told India 'stop buying oil,'" Lutnick said, adding that restricting these powers (IEEPA) would weaken Trump's ability to make "the world and the US a safer place." Expressing confidence, he said that the US President will win the case because "these powers protect America".

Trump imposed 25 per cent reciprocal tariffs on India and an additional 25 per cent levies for Delhi’s purchases of Russian oil, bringing the total duties imposed on India to 50 per cent.

India had described the US action as "unfair, unjustified and unreasonable".

In September, the Trump administration told the US Supreme Court that it imposed tariffs against India for purchasing Russian energy products “to deal with a preexisting national emergency regarding Russia’s war in Ukraine” and as a “crucial aspect” of the President’s push for peace in the country.

Trump has also been claiming for the past few days that Delhi has assured him that it will significantly reduce its oil imports from Russia.

However, India has been maintaining that its energy policy is guided by its own national interest, especially ensuring affordable and secure supplies for its consumers. PTI GRS GRS GRS

Emergency powers to impose tariffs defended as national security and diplomatic tool limiting constraints on executive trade authority Whether the executive lawfully used emergency powers to impose sweeping reciprocal tariffs raises the central legal issue: the permissible scope of statutory emergency authority to regulate international trade and duties for foreign policy and national security objectives. The administration defends the tariffs as a diplomatic and security instrument to address an international crisis, while the targeted state calls the measures unfair and insists its energy policy is guided by national interest and supply security.
