The two men spoke over the phone about the creation of a possible safe zone in Syria, the White House said. The Trump administration said it will pull U.S. troops out of the war-torn country, and has sought assurances from Turkey that it will not attack Kurdish fighters in the region.

Turkish state media said Trump and Erdogan agreed to see through the U.S. withdrawal from Syria in a way that benefits both countries. The two sides also discussed trade.

Thursday's phone call came as Acting Defense Secretary Patrick Shanahan and Chairman of the Joint Chiefs of Staff Joseph Dunford are set to host their Turkish counterparts this week in Washington, D.C.

Trump earlier this month nominated David Satterfield to be the U.S. ambassador to Turkey and fill a previously vacant post.

U.S.-Turkey relations have drawn heightened attention after Trump announced in December that the U.S. would withdraw its troops from Syria.

The administration has since put conditions on a full withdrawal of troops, including the total defeat of IS and assurances from Turkey that it will not target U.S.-backed Kurdish fighters in Syria.

U.S. support for the Kurds in Syria has been a point of tension in U.S.-Turkey relations, as Ankara views the Kurdish forces in Syria as a terrorist group.

Trump later threatened to “devastate Turkey economically” if the country's forces went after the Kurds in Syria.
