How? CMI is taking a three-pronged approach. First, it will try to diversify the supply by bring new sources online. Second, CMI will support research into developing substitutes for rare earths, something that to date has shown marginal promise (particularly in Japan, the world's largest importer of rare earths and on-again-off-again geopolitical thorn in China's side). And finally, improve and encourage reusing and recycling of existing rare earths that are often thrown out with the consumer products they are packed inside.
