WASHINGTON, Nov. 22 - U.S. President Donald Trump has spoken by phone with Russian President Vladimir Putin and discussed the need to bring peace to Syria and Ukraine among other matters, the White House said.

Trump's hour-long phone call on November 21 with the Russian president came a day after Putin met with Syrian President Bashar al-Assad at the Black Sea resort of Sochi, RFE/RL reported.

The two leaders also discussed ways to implement "a lasting peace in Ukraine," as well as the need to keep up international pressure on North Korea "to halt its nuclear weapon and missile programs," the White House said.

The White House said Trump and Putin discussed the need to revive UN negotiations "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."

Putin informed Trump of "the main results" of his meeting with Assad, "at which the Syrian leader confirmed his commitment to the political process, [and] conducting constitutional reform and presidential and parliamentary elections," the Kremlin said.

The White House said the two leaders also "affirmed the importance of fighting terrorism together throughout the Middle East and Central Asia" and agreed to look into ways to step up cooperation in the fight against Islamic State (IS), Al-Qaeda, the Taliban, and other extremist groups.

Afterwards, Trump said it was a "great call" as he left the White House to spend the U.S. Thanksgiving holiday in Florida.

Trump noted the length of the call, and said he and Putin spoke "very strongly about bringing peace to Syria," which he said was "very important."

The conversation came after Trump and Putin spoke informally several times earlier this month when they attended a summit in Vietnam, where they issued a joint statement on November 11 agreeing that a political solution was needed on Syria and that they would continue efforts to fight IS.

Trump at the time called that joint document "extraordinarily important." (rfe/ez)
