US President Joe Biden has ordered a Chinese-owned cryptocurrency miner and its partners to sell land they own near a US nuclear missile base, citing spying concerns.

MineOne Partners, which the White House says is majority-owned by Chinese citizens, has been given 120 days to sell the property, where it runs a crypto-mining operation.

The land is less than a mile (1.6km) away from an air force base in Wyoming, where intercontinental ballistic missiles are stored.

BBC News has contacted MineOne Partners and China’s embassy in the US for comment.

“The proximity of the foreign-owned Real Estate to a strategic missile base… and the presence of specialised and foreign-sourced equipment potentially capable of facilitating surveillance and espionage activities, presents a national security risk”, the White House said in a statement.
