* Analysts see USDA raising U.S. soy ending stocks view
* Traders seek more clues on U.S.-China trade dispute
* USDA expected to trim U.S. corn yield, ending stocks
* Wheat mixed; weaker dollar lends support
(New throughout; updates prices, adds quotes, changes byline, dateline, previous PARIS/SYDNEY) CHICAGO, Nov 7 (Reuters) - U.S. soybean futures fell Wednesday as traders adjusted positions the day before a monthly report from the U.S. Department of Agriculture in which the government is expected to raise its forecast of U.S. soy stocks. Corn futures eased while wheat was mixed. As of 12:53 p.m. CST (1853 GMT), Chicago Board of Trade January soybeans were down 4-1/2 cents at $8.79-3/4 per bushel after dipping to $8.76-3/4, the contract's lowest since Nov. 1. CBOT December corn was down 1 cent at $3.72-1/4 a bushel while December soft red winter wheat was up 1/4 cent at $5.12-1/4 a bushel. Analysts surveyed by Reuters on average expect the USDA on Thursday to trim its estimate of the U.S. soybean yield but raise its forecast of soy stocks left at the end of the 2018/19 marketing year. Rising ending stocks would likely reflect slowing soy export demand, with Washington and top global soy buyer China locked in a trade dispute. "Yields are coming down a bit, but the bottom line is our demand leaves a lot to be desired," said Tom Fritz, a partner with EFG Group in Chicago. The United States and China will hold top-level diplomatic and security talks, which were supposed to be held in Beijing in October, in Washington on Friday, amid moves to try to resolve a damaging trade war. However, with South American soy harvesting set to begin as early as December, the window for a recovery in U.S. exports may be closing. "We will maybe pick up some exports if things (talks with China) go well. But Brazil is ready to start aggressively exporting again in mid-January because they got their crop in so early," said Matt Connelly, analyst with the Hightower Report. Corn futures followed soybeans lower. CBOT wheat futures were choppy as traders digested conflicting grain export estimates from Russia, the world's top wheat exporter. Russia's agriculture ministry kept its grain export forecast for 2018/19 at 38 to 39 million tonnes, withdrawing an earlier lower forecast given by one of its officials. A weaker dollar lent support, making U.S. grains more competitive globally. The dollar softened after midterm elections split power in the U.S. Congress, giving Democrats greater ability to check any major initiatives from President Donald Trump. But rallies were capped by sluggish export demand for U.S. wheat, a factor that pressured K.C. and Minneapolis wheat futures. "Everybody and their neighbor is aware that U.S. wheat export stink," Fritz said.
