Mexico's government took a hardline approach to lithium in 2022, nationalizing its lithium resources and canceling mining concessions held by private companies, including those of China-based Ganfeng Lithium. According to the SCMP report, Ganfeng has since filed an arbitration case against the Mexican government over the canceled contracts. The arbitration process could drag on for years, leaving China's access to Mexico's lithium reserves in limbo.
