US, UK vow to cut external backing for Sudan belligerents

December 10, 2025 (WASHINGTON) – The United States and the United Kingdom have pledged to intensify their coordinated pressure to secure an unconditional humanitarian truce in Sudan, aiming to cut off external support for the warring parties.

The announcement was made by Massad Boulos, the US Senior Advisor for Africa, following a meeting with UK Foreign Secretary Yvette Cooper in Washington on Tuesday.

“Productive discussion with UK Foreign Minister Yvette Cooper as we work together to secure an unconditional humanitarian truce in Sudan,” Boulos said in a statement.

The US official emphasized that both nations have renewed their commitment to “cut external financial and military backing for the belligerents and to push forward coordinated pressure that can help stop the violence and ease human suffering.”

The discussions coincided with Cooper’s visit to Washington to meet with US Secretary of State Marco Rubio. The British Foreign Secretary highlighted that her agenda focused on “the biggest challenges we face,” explicitly listing “ending the bloodshed in Sudan” as a top priority.

Cooper also noted that her talks with Rubio covered securing a just and lasting peace in Ukraine, implementing a 20-point plan in Gaza, and supporting security in the Indo-Pacific.

The move signals a trans-Atlantic alignment on the Sudan crisis, leveraging the influence of the US administration to force the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF) to cease hostilities and allow humanitarian access.
