From the Congressional study: Supply Chain Vulnerabilities from China in U.S. Federal Information and Communications Technology - APRIL 2018
"The supply chain threat to U.S. national security stems from products produced, manufactured, or assembled by entities that are owned, directed, or subsidized by national governments or entities known to pose a potential supply chain or intelligence threat to the United States, including China. These products could be modified to (1) perform below expectations or fail, (2) facilitate state or corporate espionage, or (3) otherwise compromise the confidentiality, integrity, or availability of a federal information technology system." more
