US Imposes New Sanctions on Sudan Forces Over Chemical Weapons Use

The U.S. government officially announced a new round of sanctions against the Sudanese Armed Forces (SAF) this week, citing allegations that the military organization has used chemical weapons, including chlorine, against civilians and rival factions during the civil war that has persisted for over a year. Led by the U.S. Department of the Treasury, the sanctions aim to further sever the military junta’s access to funding and international financial channels in response to the escalating humanitarian catastrophe on the ground and to strongly condemn violations of international conventions prohibiting chemical weapons.

Since the Sudanese civil war erupted in April 2023, the power struggle between the SAF and the paramilitary Rapid Support Forces (RSF) has rapidly escalated into a nationwide armed conflict. The war has claimed tens of thousands of lives and displaced more than 10 million people, triggering one of the most severe refugee crises of the modern era. As the fighting remains deadlocked, both sides have frequently ignored international calls for a ceasefire in their pursuit of strategic strongholds. Recent reports of the military government using banned chemical agents in war zones such as North Darfur have been characterized by UN human rights experts as a dangerously escalatory move that severely violates international humanitarian law.

Faced with pressure from the international community, the Sudanese military junta has consistently denied the allegations of chemical weapons use, accusing Western nations of interfering in its internal affairs and attempting to install proxy forces. However, the U.S. Department of State maintains that satellite imagery, witness testimonies, and medical records of victims provide sufficient evidence that chlorine has been utilized in military operations. The sanctions will freeze the U.S.-based assets of relevant military commanders and prohibit U.S. citizens and businesses from engaging in transactions with the sanctioned targets. Furthermore, the move serves as a warning to the international financial system to prevent the Sudanese military junta from using overseas accounts to launder money or procure armaments.

Although Western nations have repeatedly attempted to facilitate peace talks through diplomatic mediation, the peace process has stalled multiple times due to a lack of mutual trust between the warring parties and the geopolitical maneuvering of regional powers. The United Nations and the African Union (AU) are currently calling on countries to implement stricter arms embargoes on Sudan to prevent the conflict from spreading to neighboring countries and triggering a regional humanitarian collapse. While the U.S. sanctions are significant, their practical effectiveness in curbing the conflict remains to be seen in the absence of unified international action.

For Taiwan, although direct economic and geopolitical ties with Sudan are limited, this event reflects a growing international trend where non-state actors and military regimes employ increasingly extreme tactics in modern regional conflicts. Moreover, the crossing of the international "red line" regarding the use of chemical weapons poses a challenge to global arms control norms. For Taiwanese readers, monitoring such conflicts not only enhances understanding of the geopolitical situation in Africa but also serves as a reminder that in the complex game of international politics, humanitarian crises are often closely intertwined with the stability of the international order. Observing how the U.S. manages such sanctions involving human rights and international conventions provides a vital window into the shifting rules of contemporary international politics.
