Indonesia's nickel ore export ban (2020)
Indonesia stopped exporting unprocessed nickel ore to force smelting investment at home. Chinese companies poured billions into processing plants on Sulawesi and neighboring islands.
Smelting capacity surged and nickel export values rose; the European Union filed a World Trade Organization complaint over the ban.
Indonesia extended export curbs to bauxite and copper concentrate, and its nickel processing complex became central to global battery supply chains.
A live test of the same bet Ethiopia is making: restrict or redirect raw exports to capture downstream processing value at home.
