CBOT corn futures down on ideal planting conditions

CHICAGO, May 8 (Reuters) - Chicago Board of Trade corn futures slipped on Thursday on good planting weather and growing conditions while traders positioned ahead of this weekend's U.S.-China trade talks.

• Ideal U.S. weather and hopes for a thawing U.S.-China trade relationship have overridden bullishness from brisk export demand, analysts said.

• Dry weather in the U.S. corn belt has allowed farmers to rapidly plant what is expected to be a large corn crop, and rainy forecasts for the coming weeks should allow for ideal growing conditions, analysts said.

• The U.S. Department of Agriculture on Monday is expected to report a sharp increase in U.S. corn production this year, lifting U.S. ending stocks above 2 billion bushels, according to an analyst poll.

• The USDA said exporters sold a net 1,662,500 metric tons of U.S. corn in the week ended May 1, above trade expectations. New-crop sales were near the low end of a range of trade estimates at 18,000 tons. Total sales were the largest in three months, USDA data showed. EXP/CORN
