1. Which groups benefitted the most from China imposing an export quota on rare earth metals? Did it give the Chinese domestic manufacturers a significant cost advantage? Did it result in dramatically increased quality and environmental standards?
2. Given that 97 percent of rare earth metal production is now done in China, an increase from 27 percent to 97 percent between 1990 and 2010, do you think countries such as Australia, Canada, and the United States should reconsider their environmental restrictions on product of such metals?
3. The restrictions imposed by China on rare earth metals has resulted in some companies (e.g., Toyota, Renault, Tesla) starting to look for alternatives. They plan to use parts that do not include rare earth metals. Is this a good solution?
