President Trump signed the Lindsey Graham-named sanctions bill at the White House on Friday, but Russia warns the legislation could undermine his peace efforts in Ukraine. The law mandates enforcement of existing sanctions against Russia, including those targeting President Vladimir V. Putin, and grants authority to impose up to 100% tariffs on nations importing Russian oil and gas, 500% tariffs on Russian imports, and measures against Russia's "shadow fleet" of oil tankers. However, it includes a national security waiver provision allowing Trump to bypass requirements with Congressional notification.

Kremlin spokesman Dmitri S. Peskov called the law an "unfriendly action" that would "complicate efforts to reach a peaceful resolution." The Russian Embassy in Washington said it would do a "grand disservice" to Trump's agenda. Former President Dmitri A. Medvedev labeled it a "Russophobic abomination" and urged military deterrence. Meanwhile, Alexander Gabuev of the Carnegie Russia Eurasia Center predicted Trump would "sign it and issue waivers." Russian lawmaker Grigory Karasin downplayed the impact, citing ongoing U.S.-Russia relationship building. President Volodymyr Zelensky of Ukraine thanked Trump for signing the bill, praising Senator Graham's resolve.
