Adds the Secretary of Agriculture as a member of the Committee on Foreign Investment in the United States (CFIUS) for certain agriculture-related matters and requires CFIUS to consider and decide whether specified agricultural land transactions involving covered foreign countries are "covered transactions." If CFIUS determines a transaction is covered, the Committee must decide whether to open a review or take other authorized action. The change includes a sunset tied to removal of particular countries from the list of foreign adversaries and defines which countries are treated as covered countries.
