U.S. President Donald Trump has issued a sharp warning to Russian President Vladimir Putin, vowing to impose unprecedented tariffs and sanctions if the war in Ukraine does not cease within 50 days.
Speaking at a press briefing on Monday, Trump signaled a hardline shift in his approach to the ongoing conflict, declaring that the United States is prepared to impose secondary tariffs of up to 100% on key Russian exports, including fertilizers, inorganic chemicals, and nuclear materials.
“Putin is all talk,” Trump said. “We will no longer tolerate attacks on Ukrainian civilians and the destabilization of Europe. If peace isn’t reached in 50 days, Russia will face tariffs like never before.”
Trump’s remarks were delivered alongside NATO Secretary-General Mark Rutte, underscoring a unified front with transatlantic allies.
As part of the broader strategy, Trump pledged increased U.S. military assistance to Ukraine, with NATO members coordinating the financing and supply of additional weaponry to bolster Kyiv’s defense.
“This move ensures Ukraine receives the defense capabilities it needs, and gives European allies the opportunity to fund peace and stability,” said Rutte, who welcomed the U.S. initiative as a timely reinforcement of NATO’s collective defense posture.
The proposed tariffs would severely impact core Russian exports, many of which are vital to global supply chains. Prior to Russia’s 2022 invasion of Ukraine, bilateral trade between Moscow and Washington exceeded $36 billion annually. That figure has since collapsed to less than 10% of its pre-war volume.

If implemented, the 100% tariffs could render many Russian imports uncompetitive in the U.S. market, especially in critical sectors such as agriculture and energy infrastructure.
However, Trump acknowledged that tariffs alone might not be enough to cripple the Russian economy, which was valued at $2.4 trillion as of 2024.
To strengthen the pressure, the Trump administration is preparing a package of secondary sanctions targeting third-party countries—especially NATO members—that continue to import Russian oil and gas.
The White House noted that while some NATO nations have significantly reduced dependence on Russian energy, others continue to provide Moscow with vital revenue streams.
Analysts estimate that Russia still earns over $300 billion annually from oil and gas exports, with NATO members accounting for nearly one-third of those earnings.
Given that fossil fuel revenues constitute over 60% of Russia’s exports and nearly a third of its government income, the proposed sanctions could have a profound impact on its war-financing capabilities.
Despite the bold announcement, experts warn that enforcement could prove difficult. Russia has previously demonstrated resilience and adaptability in the face of global sanctions, often rerouting trade through sympathetic or neutral countries.
“Tariffs and sanctions are powerful tools, but their success hinges on robust global coordination and airtight enforcement,” said Dr. Elise Gardner, a senior fellow at the Center for Strategic and International Studies. “Russia’s ability to evade restrictions through shadow networks and alternative markets is well-documented.”
