US President Donald Trump held separate telephone talks with Russian President Vladimir Putin and Ukrainian President Volodymyr Zelensky on Saturday, with the war in Ukraine dominating discussions ahead of this week's NATO summit in Ankara.
The Kremlin and the Ukrainian presidency said the calls also marked the 250th anniversary of US independence.
According to Kremlin foreign policy adviser Yuri Ushakov, Trump and Putin discussed efforts to reach a settlement in Ukraine in the context of the NATO summit, which is scheduled to take place in Ankara on 7 and 8 July.
"The presidents naturally addressed the issue of a settlement in Ukraine, taking into account, in particular, Donald Trump's upcoming participation in the NATO summit in Turkey on July 7 and 8," Ushakov told Russia's RIA Novosti news agency.
He said the 85-minute conversation also covered Iran and wider developments in the Middle East.
Earlier on Saturday, Volodymyr Zelensky described his own call with Trump as "a very good phone call", saying they discussed both the situation on the battlefield and ongoing diplomatic efforts.
"President Trump and I discussed the current situation on the frontline as well as our diplomatic efforts. There is a real prospect to put an end to this war, and America's resolve is decisive. We have agreed to continue these discussions during the NATO Summit in Ankara," Zelensky wrote on X.
Leaders and delegations from NATO's 32 member states, including Trump, are expected to arrive in the Turkish capital for the summit beginning on Tuesday.
The Kremlin said Putin told Trump that Russian forces were "advancing confidently" on the battlefield. However, military operations have changed little in recent months, with the widespread use of drones restricting the movement of heavy equipment and causing significant losses on both sides.
Diplomatic efforts also remain stalled. Moscow continues to demand that Ukrainian forces withdraw from the entire Donetsk region, a condition that Kyiv has repeatedly rejected.
