India has warned the United States that a new law letting President Trump slap tariffs of up to 100% on buyers of Russian oil could damage relations between the two countries.

Some shit you should know before you dig in: India is the world’s third-largest oil importer, and Russia is its biggest single supplier of crude, a trade that many say has bankrolled Russia’s war effort in Ukraine. India has pushed back on pressure to cut those purchases for years, arguing that a country of 1.4 billion people needs energy that is secure, affordable, and reliable, and it says it will keep buying from a range of suppliers based on market conditions. At the same time, the US is India’s top export market, with Indian goods shipped to America climbing to $42.79 billion between April and August, up from $40.39 billion over the same stretch a year earlier, and the two countries are still working toward a trade deal after months of talks.

What’s going on now: Indian officials said they had warned the United States before Trump signed the bill into law, raising it at high levels with US officials over recent months. The law does not impose tariffs on its own but gives Trump the power to hit countries like India and China with duties of up to 100% if they keep buying Russian oil and gas. It also goes after Russia’s energy and defense sectors, its financial institutions, senior officials, and the shadow fleet of tankers Moscow uses to skirt Western restrictions, and it widens sanctions on Iran. More than 50 House Democrats voted for it.

“Its potential implications for not just the bilateral relationship but also the international energy market have been very clearly articulated by the Indian side,” India’s foreign ministry said Thursday. “The Indian side has also made clear its determination to take all necessary measures to protect its trade and economic interests.”

This all comes as Brent crude sits above $100 a barrel, with Iran’s hold on the Strait of Hormuz and the Houthi takeover of Yemen’s Red Sea coast already squeezing global supply.
