§ 141. Suspension by President
Upon satisfactory proof being given to the President, by the government of any foreign nation, that no discriminating duties of tonnage or imposts are imposed or levied in the ports of such nation upon vessels wholly belonging to citizens of the United States, or upon the produce, manufactures, or merchandise imported in the same from the United States or from any foreign country, the President may issue his proclamation, declaring that the foreign discriminating duties of tonnage and impost within the United States are suspended and discontinued, so far as respects the vessels of such foreign nation, and the produce, manufactures, or merchandise imported into the United States from such foreign nation, or from any other foreign country; the suspension to take effect from the time of such notification being given to the President, and to continue so long as the reciprocal exemption of vessels, belonging to citizens of the United States, and their cargoes, shall be continued, and no longer: Provided, That the President is authorized to suspend in part the operation of section
121 of this Appendix and section 2502 of the Revised Statutes so that foreign vessels from a country imposing partial discriminating tonnage duties upon American vessels, or partial discriminating import duties upon American merchandise, may enjoy in our ports the identical privileges which the same class of American vessels and merchandise may enjoy in said foreign country.
