Which country has the largest rare earth reserves in the world?

China's reserve is only 20 years, and Japan's is as high as 30~40 years. The real reserve is the United States. Please read the information. The amount of rare earth in the United States is one of the largest countries in the world, but the United States lists local rare earth as a strategic reserve and does not mine it locally. But in fact, in addition to local rare earth resources, the United States has the most marine property rights and control rights in the world, and is also the country with the most marine exploitation and resources, especially oil and rare earth resources. American native resources have not yet counted the area and resources of overseas territories in the American ocean. The United States pointed out that primitive ecology is maintained on the islands of the ocean, and various resources are very rich. These islands are stationed by the United States and are part of American property. In addition, the United States has the largest number of overseas alliances in the world. There are many resource exploitation bases outside the United States, which are protected by American military bases.
