The global rare earth elements market is undergoing significant shifts as Brazil emerges as a potential alternative to China's dominance, while geopolitical tensions between China and Japan disrupt traditional supply chains. Mining giants are investing heavily in Brazil's vast reserves, positioning the country as a key player in critical magnetic metals production by 2028.
Brazil's rare earth reserves have attracted attention from companies like Aclara Resources, which plans to establish an independent supply chain processing output from Brazilian and Chilean mines. The Canadian firm aims to produce enough battery materials to meet half of U.S. demand, with commercial production expected by 2028. This development comes as China's rare earth exports to Japan dropped over 80% in March-April 2026. Nikkei Asia+2
The export decline appears linked to Japanese Prime Minister Sanae Takaichi's comments on Taiwan, with China's Foreign Ministry spokesperson Lin Jian explicitly stating the restrictions aim to prevent Japan's "remilitarization and nuclear ambitions." The U.S. has intervened, urging China to lift the ban ahead of the G7 summit, highlighting how rare earths have become diplomatic leverage. Chosun Ilbo+2
