Pub. L. 89-691, tit. I, sec. 106

Sec. 106. It is the sense of Congress that any attempt by foreign nations to create distinctions because of their race or religion among American citizens in the granting of personal or commercial access or any other rights otherwise available to United States citizens generally is repugnant to our principles; and in all negotiations between the United States and any foreign state arising as a result of funds appropriated under this title these principles snail be applied as the President may determine.
