FAVORED TRADE STATUS FOR MOSCOW STILL OPPOSED The Reagan administration wants to encourage expanded trade with the Soviet Union but does not believe Moscow yet warrants most-favored-nation treatment, Deputy Secretary of State John Whitehead said. "It seems to me that more trade between us is better than less trade," he told a forum on U.S.-Soviet trade relations. To that end, the administration in January allowed foreign policy controls on the export of oil and gas equipment to the Soviet Union to lapse, he said. Also, Washington and its allies are reviewing remaining export controls in hopes of simplifying the list of prohibited items and speeding up the licensing process, he said. Whitehead said, however, the prefential treatment that comes with most-favored-nation status is out for the moment. U.S. law prohibits most-favored-nation status for countries that restrict emigration and other rights. "What we have seen so far (in improved rights under Soviet Leader Mikhail Gorbachev) are promising trends," he said. But, he added: "We don't know if they will continue, we don't know how significant they will be."
