Russia warned on Saturday that a new U.S. sanctions law could undermine President Trump’s efforts to broker peace in Ukraine.
The legislation, named for Senator Lindsey Graham, was signed by Trump at the White House.
The law grants the president broad authority to waive its requirements.
Moscow said the measure would complicate diplomatic efforts and damage bilateral relations.
Russian officials argued that the sanctions could escalate tensions rather than encourage negotiation.
The Kremlin has not yet announced specific retaliatory measures in response to the law.
Trump has previously expressed willingness to use waivers if they serve U.S. diplomatic goals.
The law’s passage reflects continued congressional pressure for a tougher stance on Russia.
