The US is set to imminently announce an easing of restrictions on providing humanitarian aid and other basic services such as electricity to Syria while still keeping its strict sanctions regime in place, according to people briefed on the matter.

The decision by the outgoing Biden administration will send a signal of goodwill to Syria's new Islamist rulers and aims to pave the way for improving tough living conditions in the war-ravaged country while also treading cautiously and keeping US leverage in place.

US officials have met several times with members of the ruling administration, led by former Al Qaeda affiliate Hayat Tahrir al-Sham, since the dramatic end on Dec. 8 of more than 50 years of Assad family rule after a lightning rebel offensive.

HTS, the faction that led the advance, has long-since renounced its former Al Qaeda ties and fought the group but they remain designated a terrorist entity by the U.S. and Washington wants to see them cooperate on priorities such as counterterrorism and forming a government inclusive of all Syrians.

The Wall Street Journal reported that the Biden administration approved the easing of restrictions over the weekend, saying the move authorizes the Treasury Department to issue waivers to aid groups and companies providing essentials such as water, electricity and other humanitarian supplies.
