U.S. Secretary of State Marco Rubio said on Thursday that Trump intends to issue waivers under the "Caesar Syria Civilian Protection Act", through which Washington imposed stiff sanctions on former President Bashar al-Assad's government and secondary sanctions on outside companies or governments that worked with it.

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.

Assad, business owners have been waiting for Washington to ease sanctions and pave the way for an economic renewal.
