GERMAN BANK SEES GOOD SOVIET TRADE PROSPECTS Soviet-West German trade is expected to develop favourably due to Moscow's increasing openness to East-West economic relations, Dresdner Bank AG's Moscow representative Michael Stein said. He told a bank presentation the Soviet Union was last year hit by the fall in world oil prices, which cut export revenue from oil-related products and natural gas, and its overseas buying power was also adversely affected by the lower dollar. Dresdner Bank economist Alfred Apholte said the Soviet Union's large currency and gold reserves had softened the impact of the dollar weakening and oil price drop.
