President Trump’s Treasury Department imposed sanctions on a Russian-based company Thursday for aiding North Korea’s nuclear weapons program.

“The United States will continue to target individuals and entities responsible for financing and supporting North Korea’s nuclear weapons and ballistic missile programs, and will continue to increase pressure on this hostile regime,” said John Smith, director of the department’s Office of Foreign Assets Control. “Treasury is working with our allies to counter networks that enable North Korea’s destabilizing activities, and we urge our partners to take parallel steps to cut off their funding sources.”
