Agriculture Secretary Brooke Rollins said the move was needed to address what she called a "massive threat" to national security.

Foreign purchases of US farmland were being used as "weapons to be turned against us," Rollins said, unveiling the National Farm Security Action Plan along with other cabinet officials.

"We see it again and again, from Chinese Communist acquisition of American farmland to criminal exploitation of our system of agriculture," she said.

"American agriculture is not just about feeding our families but about protecting our nation and standing up to foreign adversaries who are buying our farmland," she added.

China ranks number 20 on a list of foreign owners of agricultural land, holding 277,336 acres (112,234 hectares) at the end of 2023, according to the US Department of Agriculture.

Rollins said the administration of President Donald Trump also planned to "claw back what has already been purchased by China and other foreign adversaries."

Defense Secretary Pete Hegseth said the Pentagon would ban sales to "foreign adversaries" of farmland located near US military bases.

"As someone who's charged with leading the Defense Department, I want to know who owns the land around our bases," Hegseth said. "It's common sense."

"No longer can foreign adversaries assume we aren't watching," he said.

Among the largest Chinese owners of US farmland is Smithfield Foods, which was purchased by a Chinese company, WH Group, in 2013.
