The United States has imposed sanctions on two commanders from rival armed groups in eastern Democratic Republic of Congo, a move that adds pressure to Washington’s push for a negotiated end to the conflict. According to a Reuters report, the U.S. Treasury targeted John Imani Nzenze of M23 and Gustave Kubwayo of the FDLR.

The measures matter because they target figures from both sides of a conflict that has continued despite U.S.-backed mediation. M23 remains one of the most powerful armed movements in eastern Congo, while the FDLR has long been cited as a destabilizing force in the Great Lakes region.

The U.S. Treasury said the sanctions are meant to support efforts toward peace and reduce violence that has worsened an already severe humanitarian crisis. Under the measures, any assets belonging to the sanctioned individuals under U.S. jurisdiction are frozen, and U.S. persons are generally barred from doing business with them.

Local outlet Actualité.cd reported that Nzenze is described as M23’s intelligence chief, while Kubwayo, also known as “Colonel Sirkoof,” is linked to FDLR intelligence and special operations activity in North Kivu.

The sanctions also carry a broader diplomatic message. Washington has repeatedly called for Rwanda to end support for M23 and withdraw forces, while also pressing Kinshasa to neutralize the FDLR. Earlier U.S. sanctions connected to the eastern Congo conflict also targeted Rwanda’s military and senior officials, according to AP.

For eastern Congo, the immediate battlefield impact remains uncertain. But politically, the move signals that Washington is keeping pressure on armed commanders while trying to hold regional actors to previous peace commitments.
