During the lengthy conversation, the two leaders also discussed jointly fighting terrorist groups in the Middle East, including ISIS and Al-Qaeda, and the Taliban in other parts, it said.
"We had a great call with President Putin. We're talking about peace in Syria, very important. We're talking about North Korea. We had a call that lasted almost an hour and a half," President Trump told reporters before boarding Marine One on the White House lawns.
"We're talking very strongly about bringing peace for Syria. We're talking very strongly about North Korea and Ukraine," he said.
Both presidents supported the UN-led Geneva Process to peacefully resolve the Syrian civil war, end the humanitarian crisis, allow displaced Syrians to return home, and ensure the stability of a unified Syria free of malign intervention and terrorist safe havens, the White House said in a readout of the call.
"The two presidents affirmed the importance of fighting terrorism together throughout the Middle East and Central Asia and agreed to explore ways to further cooperate in the fight against ISIS, Al-Qaeda, the Taliban, and other terrorist organisations," it said.
Mr Trump and Mr Putin spoke informally several times last week when they attended a summit in Vietnam. They agreed on a number of principles for the future of war-torn Syria.
President Trump spoke over phone with the Russian president, a day after Mr Putin met with Syrian President Bashar Assad. Mr Putin hosted the Syrian president at a Black Sea resort ahead of a summit later this week with Russia, Turkey and Iran.
The Kremlin said yesterday that Mr Assad was called to Russia to get him to agree to potential peace initiatives drafted by Russia, Iran and Turkey.
