In carrying out this chapter, special emphasis shall be placed on procurement in the United States, but, subject to the provisions of subsection (b) of this section, consideration shall also be given to coproduction or licensed production outside the United States of defense articles of United States origin when such production best serves the foreign policy, national security, and economy of the United States. In evaluating any sale proposed to be made pursuant to this chapter, there shall be taken into consideration (A) the extent to which the proposed sale damages or infringes upon licensing arrangements whereby United States entities have granted licenses for the manufacture of the defense articles selected by the purchasing country to entities located in friendly foreign countries, which licenses result in financial returns to the United States, (B) the portion of the defense articles so manufactured which is of United States origin, and (C) whether, and the extent to which, such sale might contribute to an arms race, aid in the development of weapons of mass destruction, support international terrorism, increase the possibility of outbreak or escalation of conflict, or prejudice the development of bilateral or multilateral arms control or nonproliferation agreements or other arrangements.

No credit sale shall be extended under section 2763 of this title, and no guarantee shall be issued under section 2764 of this title, in any case involving coproduction or licensed, production outside the United States of any defense article of United States origin unless the Secretary of State shall, in advance of any such transaction, advise the appropriate committees of the Congress and furnish the Speaker of the House of Representatives and the President of the Senate with full information regarding the proposed transaction, including, but not limited to, a description of the particular defense article or articles which would be produced under a license or coproduced outside the United States, the estimated value of such production or coproduction, and the probable impact of the proposed transaction on employment and production within the United States.

Funds made available under this chapter may be used for procurement outside the United States only if the President determines that such procurement will not result in adverse effects upon the economy of the United States or the industrial mobilization base, with special reference to any areas of labor surplus or to the net position of the United States in its balance of payments with the rest of the world, which outweigh the economic or other advantages to the United States of less costly procurement outside the United States.
