China dominates the mining and processing of rare earths. According to the USGS, in 2020 China produced 140,000 metric tons of REO equivalents, or 58.3 percent of the global supply. The next-largest producers were the United States (38,000 metric tons of REO), Myanmar (30,000) and Australia (17,000). [8]
