China's Rare Earth Export Ban Raises Concerns over National Security and Global Technology Supply

China has banned the export of technology used to extract and separate rare earth metals, a move aimed at protecting its dominance in the strategic metals sector. While Western countries are increasing their own rare earth processing operations, China's ban is expected to have the greatest impact on "heavy rare earths," where it holds a virtual monopoly. The ban is part of China's efforts to tighten control over critical minerals and protect national security. Rare earths are essential for making magnets used in electric vehicles, wind turbines, and electronics. China's advanced refining technology gives it a significant efficiency and cost advantage in the industry.
