The United States Congress clearly has the power to regulate commerce within its territorial boundaries and with foreign nations, pursuant to Article I, Section 8 of the Constitution. However, implementation of the framers' policy decision to protect American markets and provide an open economic atmosphere has created a myriad of problems and questions with the overwhelming rise of multinational corporations internationally and domestically. In early attempts to deal with anti-competitive forces, Congress in 1890 enacted the Sherman Anti-trust Act. In addition to its efforts in 1890, Congress has periodically responded to international and domestic antitrust needs. The Clayton Act of 1914, Federal Trade Commission Act of 1918, and the Wilson Tariff Act of 1894, supplement the dominant Sherman Act in regulating foreign commerce.
