This provision is vital because if a U.S. firm voluntarily acts against apartheid. as the Chrysler Corp. recently did. or if a U.S. firm conforms to the provisions of H.R. 1460 once it becomes law. a foreign firm should not be freely allowed to step into that open market. exploit cheap labor. and assume an unfair competitive advantage. There is another provision taken from H.R. 1098. which is embodied in H.R. 1460. At section 12. subsection 10. the term "political prisoner" is defined. The definition is drawn from the Refugee Act of 1980. Persecution and incarceration of political prisoners in South Africa is a major problem. This subsection is designed to help free persons like Nelson Mandela. without countenancing terrorism.
