President Trump has signed into law a sweeping sanctions bill targeting Russia and Iran, granting his administration the power to impose tariffs of up to 100 percent on countries that continue buying Russian energy. The measure, passed by the House and now enacted in Washington, is aimed squarely at pressuring Moscow over the war in Ukraine, but its most immediate diplomatic fallout is landing thousands of miles away, in New Delhi and Beijing.

India and China are the world's two largest buyers of discounted Russian crude, a trade that expanded dramatically after Western nations imposed sanctions on Moscow following its 2022 invasion of Ukraine. Both countries have publicly criticized the new law, warning that it threatens their energy security and, in India's case, could inflict serious damage on a bilateral relationship with the United States that has been carefully built over two decades. Russia, for its part, has denounced the sanctions as an act of economic coercion.

A Blunt Instrument With Global Reach

What makes the law notable is not just its severity but its scope. Rather than sanctioning Russian entities directly, it threatens tariffs on third countries that keep purchasing Russian energy, effectively asking India and China to choose between their relationship with Washington and their energy arrangements with Moscow. For India, which imports roughly 80 percent of its crude oil needs and has leaned heavily on discounted Russian barrels to keep costs down for its economy, the threat of a 100 percent tariff is not an abstraction. It raises the prospect of a serious rupture in trade relations with the United States, one of India's largest export markets and a key strategic partner in Washington's efforts to counterbalance China in Asia.

Indian officials have signaled unease that a strategic partnership built around shared concerns over China could be jeopardized by a policy that treats India's energy purchases as an offense on par with the very geopolitical rivalry the partnership was meant to address. China, already locked in a broader trade and technology standoff with Washington, has framed the sanctions as another instance of American overreach.

The Uranium Carve-Out

Yet buried within the bill is a provision that reveals the limits of Washington's willingness to sever ties with Russian energy altogether. Section 114 of the legislation explicitly exempts uranium imports and existing US-Russia civilian nuclear agreements from the sanctions regime. The reason is straightforward: according to 2025 data from the US Energy Information Administration, Russia supplies approximately 26 percent of the enriched uranium that fuels America's nuclear reactors.

That dependency has proven difficult to shed. Enriching uranium to reactor-grade purity requires specialized centrifuge technology that only a handful of countries, Russia chief among them, produce at industrial scale. Despite years of efforts to rebuild domestic enrichment capacity and diversify supply toward allies, the United States has not been able to close the gap quickly enough to risk cutting off Russian nuclear fuel without threatening its own power grid.

The exemption underscores a broader tension running through the sanctions law: Washington is willing to threaten the economic relationships of major trading partners like India in the name of isolating Russia, while carving out protection for the parts of that same Russian trade that serve America's own interests. Critics of the bill argue this selective approach undermines the moral clarity the sanctions are meant to project and gives capitals in New Delhi and Beijing grounds to accuse Washington of hypocrisy.

Echoes of Past Energy Shocks

The dispute also revives long-standing debates about the risks of overdependence on volatile energy geopolitics. Russia's own economy has weathered previous energy-driven shocks, including the collapse of oil prices in 2008, when Moscow saw crude fall from $140 to $40 a barrel in a matter of months and was forced to spend hundreds of billions of dollars propping up its banking sector and currency. That experience pushed the Kremlin to diversify into natural gas, arms exports, and nuclear technology exports to countries including China and India, the very same nuclear trade now shielded by Washington's new law.

For India, the current standoff carries echoes of past episodes in which global financial and energy pressures exposed vulnerabilities in its economy, including a stretch in the early 2010s when a widening current account deficit and rating downgrades from Standard & Poor's and Fitch strained its finances. Energy security has long been treated in New Delhi as a matter of national economic stability rather than pure geopolitics, which is part of why officials have been reluctant to simply abandon discounted Russian crude under American pressure.

What Comes Next

The law gives Trump discretion over when and how to impose the threatened tariffs, meaning the coming weeks will likely be dominated by diplomatic maneuvering rather than immediate economic rupture. Indian and Chinese officials are expected to press Washington for exemptions or delays, while the administration will have to weigh the strategic cost of alienating a key Indo-Pacific partner against its stated goal of starving the Kremlin of oil revenue.

How that balance is struck may say as much about the future of US alliances in Asia as it does about the war in Ukraine.
