Washington, Jul 31 (PTI) US President Donald Trump once again mounted a sharp attack on India and Russia for their close ties and said that the two countries can take their "dead economies down together".

The US president's fresh criticism of New Delhi and Moscow came hours after announcing 25 per cent tariffs against India, plus a "penalty" for its trade with Russia.

"I don't care what India does with Russia. They can take their dead economies down together, for all I care," he said.

"We have done very little business with India, their Tariffs are too high, among the highest in the World," he added.

Trump on Wednesday announced the imposition of a 25 per cent tariff on all goods coming from India starting August 1, plus an unspecified penalty for buying Russian crude oil and military equipment.

The surprise announcement came a day after Indian officials said that a US trade team would visit from August 25 to negotiate a trade deal.

The announcement is being seen as a pressure tactic to get New Delhi to agree to demands made by the US, which has, in recent days, got favourable trade deals with major partners like Japan, the UK and the European Union.

Trump termed India's trade policies as "most strenuous and obnoxious".

"All things not good! India will therefore be paying a tariff of 25 per cent, plus a penalty for the above, starting on August first," Trump said in a social media post.

The penalty was announced as India has made large purchases of oil and military equipment from Russia. India is the first country to face a penalty for Russian imports.

India's import of crude oil from Russia has risen from 0.2 per cent of total purchases before the Russia-Ukraine war to 35-40 per cent. New Delhi is the largest buyer of Russian oil after China.

Trump said though India is America's friend, "we have, over the years, done relatively little business with them because their (India) tariffs are far too high, among the highest in the world, and they have the most strenuous and obnoxious non-monetary trade barriers of any country".

He said India has always purchased a significant amount of military equipment and energy products from Russia at a time when everyone wants Russia to stop the "killing" in Ukraine. PTI MPB GRS GRS

Tariff imposition used as trade leverage: new duties and penalties target imports tied to third country energy and defence ties. The document reports a US executive announcement imposing a 25 percent tariff on all imports from India and an additional penalty tied to India's purchases of Russian crude oil and military equipment, justified by India's high tariffs and non monetary trade barriers and framed as leverage ahead of scheduled trade negotiations.
