The White House on Monday gave a Chinese-linked company and its partners 120 days to sell property they had bought near a U.S. Air Force base in Wyoming that is home to part of the U.S. nuclear arsenal, citing fears of spying.

The move comes as the United States has become increasingly concerned about the national security risks posed by Chinese-led purchases of American property near sensitive military sites.

MineOne Partners Limited, which is owned by Chinese nationals, partnered with other companies to buy real estate for cryptocurrency mining in June 2022, the White House said.

The property is located within 1 mile (1.6 kilometers) of Wyoming-based Francis E. Warren Air Force Base, which is home to part of the U.S. arsenal of intercontinental ballistic missiles.

"The proximity of the foreign-owned Real Estate to a strategic missile base and key element of America's nuclear triad, and the presence of specialized and foreign-sourced equipment potentially capable of facilitating surveillance and espionage activities, presents a national security risk to the United States," the White House said in a statement.

MineOne Partners did not immediately respond to a request for comment.

Reuters reported in 2022 that the Biden administration was investigating Chinese telecoms equipment maker Huawei over concerns that U.S. cell towers fitted with its gear could capture sensitive information from military bases and missile silos that the company could then transmit to China.

The MineOne Partners deal was reviewed by CFIUS, a powerful panel led by the Treasury Department that scrutinizes foreign investment in the United States for national security risks.

A 2018 law expanded CFIUS's authority to review foreign acquisitions of some non-controlling investments in U.S. real estate transactions that pose national security concerns.

The move on Monday "highlights the critical gatekeeper role that CFIUS serves to ensure that foreign investment does not undermine our national security, particularly as it relates to transactions that present risk to sensitive U.S. military installations as well as those involving specialized equipment and technologies," Treasury Secretary Janet Yellen said in a statement.

U.S. Blocks China-Tied Crypto Miners as 'National Security Risk' Near Nuke Base

• The White House says a Chinese crypto-mining operation set up shop within a mile of a U.S. nuclear missile base without getting proper clearance.

• The order to shut it down said it's using foreign-source technology that poses national-security concerns.

President Joe Biden ordered a cryptocurrency mining facility near Warren Air Force Base in Wyoming to halt operations on Monday, calling it a threat to national security.

The White House order said the British Virgin Islands company behind MineOne, which is majority owned by Chinese nationals, must remove all the improvements and mining equipment on the property located within a mile of the military facility in Cheyenne – a base that houses Minuteman III nuclear missiles.

The company, which bought the property in 2022, was accused of acquiring the land and starting work there without filing with the Committee on Foreign Investment in the United States (CFIUS), and a tip started an investigation into that acquisition, according to the White House.

The order, which also authorized the U.S. attorney general to "take any steps necessary" to enforce it, cited the "presence of specialized equipment on the property used to conduct cryptocurrency mining operations, some of which is foreign-sourced and presents significant national security concerns," according to a related statement from the Department of the Treasury.

MineOne didn't immediately respond to a request for comment sent through the company's website.
