Sudan Rejects U.S. Chemical Weapons Allegations as Fresh Sanctions Deepen Diplomatic Rift
Sudan’s diplomatic standoff with the United States has intensified after Khartoum strongly rejected new U.S. sanctions linked to allegations that its military used chemical weapons during the country’s ongoing civil war, opening a fresh chapter in an already devastating conflict that has drawn increasing international scrutiny.
The sanctions, which officially took effect on July 20, follow Washington’s determination that Sudan failed to meet the conditions required under the U.S. Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 to avoid additional punitive measures. The move comes as Sudan continues to grapple with a brutal civil war that erupted in April 2023 between the Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Forces (RSF), a conflict that has displaced millions and triggered one of the world’s worst humanitarian crises.
Sudan has dismissed the U.S. accusations as politically motivated, insisting that Washington has failed to provide credible evidence to support its claims. In a strongly worded statement, Sudan’s Ministry of Foreign Affairs accused the United States of bypassing internationally recognised procedures established under the Chemical Weapons Convention by relying on what it described as unverified allegations instead of independent investigations.
According to Sudanese authorities, any claims involving the use of chemical weapons should be investigated through internationally recognised mechanisms, particularly those overseen by the Organization for the Prohibition of Chemical Weapons (OPCW), rather than through unilateral political decisions.
Under the latest sanctions, Sudan will be denied access to loans as well as financial and technical assistance provided by the United States through multilateral development banks. The measures also impose stricter export restrictions and suspend the operating privileges of Sudanese state-owned or state-controlled airlines within the United States. However, humanitarian assistance, alongside certain essential commodities and technologies, remains exempt from the sanctions.

The dispute traces back to May 2025, when the United States publicly accused the Sudanese military of deploying chemical weapons during clashes with the Rapid Support Forces in 2024. Initial sanctions followed in June, although U.S. authorities did not disclose the type of chemical agent allegedly used or specify the location of the reported incident.
Washington maintains that Sudan violated its obligations under international law and failed to take the necessary corrective measures to prevent additional penalties. Sudan, however, continues to deny the allegations, arguing that they are unsupported by any independent findings or conclusions from the OPCW.
Khartoum has reiterated that it neither develops, possesses nor deploys chemical weapons and insists that it remains fully committed to its obligations under the Chemical Weapons Convention. Sudan says it has continued submitting the required declarations to the OPCW and remains willing to cooperate with both the United States and relevant international bodies to technically verify the allegations through established international procedures.
The latest U.S. measures come amid mounting international pressure on Sudan over its prolonged conflict. Earlier this month, the European Union also imposed a new round of sanctions targeting Sudan’s gold sector, a key source of revenue that officials believe may be helping finance the ongoing war.
The EU sanctions, approved by European ministers on July 13, introduce an embargo on Sudanese gold imports, prohibit the export of cyanide and mercury to Sudan, and tighten restrictions on the sale of Sudanese gold across member states. The measures are designed to limit economic activities that could contribute to sustaining the conflict.
The latest package represents the European Union’s first major sanctions against Sudan in several months, following earlier penalties imposed on individuals and entities associated with the warring factions.
As Sudan’s civil war enters another year, the country now faces growing diplomatic isolation alongside deepening humanitarian and economic challenges. With the United States and European Union increasing pressure through coordinated sanctions while Khartoum firmly rejects the allegations against it, prospects for easing tensions remain uncertain as the conflict continues to exact a heavy toll on the nation.
