U.S./SOVIET GRAIN MEETING UNLIKELY THIS SUMMER Prospects appear slim for a summer meeting between U.S. and Soviet officials before the two countries enter the final year of their bilateral grains agreement, Agriculture Department officials said. The two sides usually try to meet as each new year of the agreeement approaches although the last meeting was delayed up to last February. However, any delay this year should not endanger the fifth year of the grains agreement that extends through September, 1988, USDA officials said. "It will be difficult to pull together the people for the meeting during July," an aide to USDA undersecretary Daniel Amstutz said. Since the last meeting was only around four months ago, the next talks could still be a "couple more months," he said. There has been grain industry speculation that the USDA will offer Moscow another wheat subsidy during the next marketing year. But USDA officials said even if consultations were held soon a subsidy offer would probably not be made. "I doubt that there would be any subsidy offer this summer or before the next agreement year begins," a USDA source said. Citing limited subsidy funds and uncertainties about next year's crops, he said, "There are too many variables now. It would be uncharacteristic of us to make an offer now." Under the nonbinding pact, Moscow has agreed to purchase a minimum of nine mln tonnes of U.S. grain per year. Soviet and U.S. officials normally meet in the summer before the start of a new agreement year to discuss grain quality, shipping logistics and production outlooks.
