Bonn Diverse Demand

摘要

Military strategists and policymakers often say that they are not aware of the importance of long-term, secure supplies of strategic commodities, namely rare earth elements (REE), used in various components of defence weapon systems. But they were concerned that China had cut its REE exports and appeared to be restricting the world's access to them, resulting in a nearly total dependence of many western nations on China for REE, including oxides, phosphors, metals, alloys, and magnets.
