ave Japan's trade concessions resulted in more U.S. exports? One premise of the more results-oriented trade policy toward Japan now being pursued is that past concessions have not caused U.S. exports to Japan to rise. The only success story seems to be that of semiconductors in which a specific goal of 20 percent of the Japanese market was set and attained.

Japan's sea shipment of a ton of plutonium from France to Japan on Nov. 7, 1992, faced strong public opposition, as did a previous one in 1984, from various public interest groups, independent analysts, and Members of Congress. The shipment arrived safely in Tokyo Jan. 4, 1993. Several more shipments at intervals of about 3 years are expected. While the plutonium is owned by Japanese utilities, it was produced from uranium enriched in the United States and supplied under a U.S.-Japan agreement for nuclear cooperation, revised in 1988. Although the agreement ties some strings to what Japan can do with nuclear imports from the United States, it also in effect gives to Japan a 30-year advance consent to ship plutonium subject to informing the United States.

On May 25, 1989, President Bush proposed that the United States undertake the Structural Impediments Initiative (SII), a series of discussions with Japan to address certain fundamental Japanese economic policies and business practices that the United States claims impede U.S. exports and investments. The SII was, in part, a Bush Administration response to the stubborn U.S. trade deficit and other problems that have caused friction in the U.S. trading relationship with Japan. It was also a response to congressional pressure to deal more aggressively with Japanese unfair trade practices and to calls from critics to adopt a "managed" trade policy toward Japan.
