SOVIET ECONOMIST SEES FEW GAINS IN U.S. TRADE There is little chance Soviet exports to the United States will rise in 1987, but Moscow's current trade reforms should result in more trade in manufactured goods in future, a Soviet economist said. Sergey Frolov, chief economist at Amtorg Trading Corp, an agent for Soviet trade organisations and industries, told a U.S.-USSR business meeting the Soviet Union produces few items that western nations want. But reforms, including upgrading the quality of goods and allowing joint ventures with foreign firms, will encourage modest export gains in future. Frolov said the Soviet Union exported 500 mln dlrs worth of goods to the United States in 1986 and imported 1.5 billion dlrs worth. He gave no trade forecast for 1987. But he said that even if all obstacles were removed, total trade between the two countries would remain between two and three billion dlrs a year. "The post-detente embargoes have taught the USSR to limit its trading with the U.S.," he said.
