WHITE HOUSE UNIT DECIDES ON SEMICONDUCTORS The White House Economic Policy Council made a recommendation to President Reagan whether to retaliate against Japan for alleged unfair practices in semiconductor trade, U.S. officials said. They would not disclose the council's recommendation, but the officials said earlier it was likely the council would call for retaliation and urge that curbs be imposed on Japanese exports to the United States. The officials said it might be several days before Reagan would act and his moves made public. The Senate last week unanimously called on Reagan to impose penalities on Japanese exports. Retaliation was also called for by the semiconductor industry and its chief trade union, both hard hit by Japanese semiconductor trade. In a pact last summer, Japan summer agreed to stop dumping its semiconductors at less than cost in the United States and other nations and to open its own market to the U.S. products. In return, the United States agreed to hold up imposing anti-dumping duties on Japanese semiconductor shipments. U.S. officials say that while Japan has stopped dumping semiconductors on the American market, they have continued to dump them in third countries and that the Japanese market has remained all but closed to the U.S. semiconductors. semiconductors on the American market, they have continued to dump them in third countries and that the Japanese market has remained all but closed to the U.S. semiconductors.
