Mandiant reported that the pro-PRC influence operation DRAGONBRIDGE targeted rare earths mining companies in an effort to weaken competitors to the PRC’s dominance in the global rare earths market. The campaign focused on shaping public perception around mining projects and companies involved in developing alternative supply chains outside China, using coordinated online narratives intended to erode support for those operations.
The activity reflects a broader use of information operations to advance strategic economic interests, with rare earths remaining critical to technology, defense, and industrial manufacturing. By aiming messaging at firms and projects that could expand non-PRC production, the campaign sought to hinder market rivalry and preserve the PRC’s leverage over a sector central to global supply chains.
