The U.S. sanctioned six individuals and five entities based in China for supporting North Korea's weapons programs on Wednesday, revealing a network of companies that allegedly helped Pyongyang procure parts for ballistic missiles and satellites.

In a press release, the Treasury Department’s Office of Foreign Assets Control (OFAC) said the new sanctions build on its 2023 designation of Choe Chol Min, a Beijing-based representative of the DPRK’s Second Academy of Natural Sciences responsible for developing “advanced weapons systems.”
