A high-stakes phone call between U.S. President Donald Trump and Russian President Vladimir Putin on Tuesday produced modest progress toward reducing the fighting between Russia and Ukraine but failed to secure the full cease-fire that Trump had been seeking.

According to a Kremlin readout of the call, Putin agreed to pause strikes on Ukraine’s “energy and infrastructure” for 30 days and “immediately gave the Russian military the corresponding order.” Ukrainian authorities have repeatedly accused Moscow of “weaponizing winter” by targeting critical energy facilities in large-scale missile and drone attacks, and even after the call, the Ukrainian Air Force reported several Russian drones, ballistic missiles, and guided bombs in the air.

Washington and Moscow also agreed to immediately begin “technical negotiations on implementation of a maritime ceasefire in the Black Sea, full ceasefire and permanent peace,” according to the U.S. readout. The Kremlin’s readout added that the two parties agreed to organize hockey matches between Russian and U.S. players.

On Truth Social, Trump described the call, which lasted at least 90 minutes, as a “very good and productive one.” Yet he did not mention that Putin had rejected the full cease-fire that the United States was pushing for.

Earlier this month, Ukrainian President Volodymyr Zelensky proposed a limited air and sea truce, but the White House convinced Kyiv to support a U.S.-proposed full cease-fire instead. That was what Trump was aiming to secure on Tuesday, only for Putin to ultimately agree to something closer to where Zelensky originally stood.
