Applies the definition of "exchange-rate manipulation" to the Government of the People's Republic of China (PRC) or any other public entity within its territory.

Directs the Secretary of Defense, upon proper request or resolution, to report to the U.S. International Trade Commission any determination as to whether or not the articles of the PRC that are the subject of the investigation are like or directly competitive with domestically produced articles critical to the U.S. defense industrial base.
Prohibits the Secretary from procuring, directly or indirectly, such products if the Commission or the President or the U.S. Trade Representative makes an affirmative determination that the Secretary's determination is accurate.
Provides for presidential waiver of the prohibition in the national security interests of the United States.
