An end to U.S. sanctions on Syria is expected to mark a new era for an economy devastated by 13 years of war, opening the way for investment flows from the Syrian diaspora, Turkey, and Gulf states that back the new government.

A White House readout of Trump's meeting with the Syrian leader said the president asked Syria to adhere to several conditions in exchange for sanctions relief, including telling all foreign terrorists to leave Syria, deporting "Palestinian terrorists," and helping the U.S. prevent the resurgence of ISIS.
