A Swiss mining company has threatened the Guatemalan government with an investment arbitration case after its nickel mining operations got shuttered two years ago.

The mining operations ceased after the U.S. Treasury Department Office of Foreign Assets Control imposed sanctions in late 2022 on Mayaniquel, a unit of Switzerland's International Metal Supply Holding, for alleged bribery of Guatemalan officials perpetrated by a Russian national who was employed by another nickel miner.
