The importance which our manufactures have assumed in the commerce of the world in competition with the manufactures of other countries again draws attention to the duty of this Government to use its utmost endeavors to secure impartial treatment for American products in all markets. Healthy commercial rivalry in international intercourse is best assured by the possession of proper means for protecting and promoting our foreign trade. It is natural that competitive countries should view with some concern this steady expansion of our commerce. If in some instance the measures taken by them to meet it are not entirely equitable, a remedy should be found. In former messages I have described the negotiations of the Department of State with foreign Governments for the adjustment of the maximum and minimum tariff as provided in section 2 of the tariff law of 1909. The advantages secured by the adjustment of our trade relations under this law have continued during the last year, and some additional cases of discriminatory treatment of which we had reason to complain have been removed. The Department of State has for the first time in the history of this country obtained substantial most-favored-nation treatment from all the countries of the world. There are, however, other instances which, while apparently not constituting undue discrimination in the sense of section 2, are nevertheless exceptions to the complete equity of tariff treatment for American products that the Department of State consistently has sought to obtain for American commerce abroad. NECESSITY FOR SUPPLEMENTARY LEGISLATION These developments confirm the opinion conveyed to you in my annual message of 1911, that while the maximum and minimum provision of the tariff law of 1909 has been fully justified by the success achieved in removing previously existing undue discriminations against American products, yet experience has shown that this feature of the law should be amended in such way as to provide a fully effective means of meeting the varying degrees of discriminatory treatment of American commerce in foreign countries still encountered, as well as to protect against injurious treatment on the part of foreign Governments, through either legislative or administrative measures, the financial interests abroad of American citizens whose enterprises enlarge the market for American commodities.
