US President Donald Trump's punitive 50 per cent tariff on imports from India could pose a serious challenge to New Delhi's self-reliance ambitions under the Atmanirbhar Bharat mission.

India faces a potential $9-12 billion increase in crude oil import expenses if it halts Russian oil purchases due to potential tariffs. While India has diversified its oil sources, Russian oil accounts for a significant portion of its imports.

U.S. President Donald Trump issued an executive order on Wednesday imposing an additional 25% tariff on goods from India, saying the country directly or indirectly imported Russian oil.
