Wrong. Lithium in Chile was nationalized in the 1980s by Pinochet. Lithium extraction and processing has been granted to privates in long term contracts that will continue to be valid but will not be renewed, and new mines will be owned directly by the state.

They've announced plans to do so and those plans have issues and wil take time:
