The Committee on Foreign Investment in the United States (CFIUS)
is a committee of representatives of nine federal agencies tasked
with reviewing investments in, or acquisitions of, U.S. companies
by foreign investors for national security concerns and
recommending to the President whether to block such transactions.
CFIUS has traditionally lived in the shadows of the Department of
Justice's and Federal Trade Commission's antitrust merger
reviews, but with the rise of foreign investment in U.S. companies,
particularly Chinese investment in the high-tech sector, and
heightening global trade tensions, CFIUS has stepped into the
limelight with a more aggressive posture, and Congress has enacted
legislation to grant CFIUS new powers.
