The US Treasury Department on Friday imposed a new package of sanctions on entities and individuals accused of supplying weapons and fighters to both sides in Sudan's civil war, in a move that narrows the financing margins of a conflict that has raged for more than three years between the Sudanese Armed Forces and the Rapid Support Forces.

The sanctions, issued by the Office of Foreign Assets Control (OFAC), targeted procurement networks that the office said had enabled both parties to the conflict to expand and intensify the fighting, deepening one of the world's worst humanitarian crises, destabilising an already fragile region, and creating fertile ground for the growth of terrorist groups in ways that threaten US interests and security.

US Treasury Secretary Scott Bessent said that President Donald Trump's administration is committed to advancing peace efforts in Sudan and ending the conflict, stressing that networks profiting from the war are obstructing opportunities to reach the humanitarian truce that Sudanese people urgently need.

Washington renewed its call on both parties to the conflict to accept an immediate, unconditional three-month humanitarian ceasefire that would allow aid to reach those in need, protect civilians, and open the door to negotiations leading to a permanent halt to hostilities.

The action was taken under Executive Order 14098, titled "Imposing Sanctions on Persons Destabilizing Sudan and Undermining the Goal of a Democratic Transition," following an investigation conducted by the office in cooperation with the National Targeting Center of US Customs and Border Protection.

Detailing the targets on the military's side, the office pointed to the Defence Industries System (DIS), the country's largest defence institution, which supplies the army with weapons, ammunition, and vehicles — often procured from external backers. The system controls a broad network of subsidiaries through complex ownership structures, including the Giad Industrial Group, known as Sudan Master Technology; the Treasury had listed both the system and the group in June 2023.

The sanctions also hit Target Multiactivities (TMAC), which is controlled by DIS through the Giad Group. According to the office, the company imported explosives from external sources including SBL Energy, which supplied it with more than 200 shipments since 2024. The office also listed Ports Engineering for Construction, which is owned by Sudanese government institutions.

The measure comes as one link in a continuous chain of sanctions that Washington has imposed since the war erupted on 15 April 2023, targeting leaders and companies on both sides with the aim of pushing the two parties toward the negotiating table.
