CHICAGO, May 15 (Reuters) - The following are U.S. expectations for the resumption of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CDT (1330 GMT) on Friday:

WHEAT - Down 9 to 10 cents per bushel

• CBOT wheat Wv1 futures ticked down with a forecast for rain in the U.S. Plains helping to pull back prices from a two-year peak hit earlier in the week. GRA/

• Crop scouts on the second day of an annual three-day tour of Kansas projected an average yield for hard red winter wheat in the southwestern portion of the state at 39.3 bushels per acre (bpa), down from 53.3 bpa in 2025.

• In the parched U.S. southern Plains wheat belt, showers are expected to arrive in the 6-15 period, but the relief will come too late for most of the winter wheat crop, according to forecaster Commodity Weather Group.

• CBOT July soft red winter wheat WN26 was last down 10 cents at $6.48 a bushel. K.C. July hard red winter wheat KWN26 was last down 11 cents at $6.94-1/4 a bushel, and Minneapolis July spring wheat MWEN26 was down 8-1/4 cents at $6.94-1/4 a bushel.

CORN - Down 4 to 6 cents per bushel

• CBOT corn futures ticked lower as disappointment over the outcome of the summit between U.S. President Donald Trump and Chinese President Xi Jinping in Beijing outweighed the prospect of additional U.S. domestic demand from corn-based ethanol.

• The meeting failed to produce deals for fresh Chinese purchases of U.S. soybeans and other farm goods. GRA/

• The Incheon section of the Korea Feed Association (KFA) in South Korea purchased about 68,000 metric tons of animal feed corn expected to be sourced from South America or South Africa in a private deal on Friday without issuing an international tender, European traders said. GRA/TEND

• CBOT July corn CN26 was last down 5-3/4 cents at $4.61-3/4 per bushel.

SOYBEANS - Down 11 to 13 cents per bushel

• Soybean futures headed down on Friday, adding to heavy losses from the previous session after a U.S.-China summit dented demand sentiment.

• Market expectations had been moderate given Beijing had not been expected to go beyond a previous commitment to buy 25 million metric tons annually from next season. But traders had still hoped for some new purchase deals from the meeting. GRA/

• U.S. Trade Representative Jamieson Greer said on Friday that Washington expects "double-digit billions" in Chinese purchases of U.S. agricultural products over the next three years.

• CBOT July soybeans SN26 were last down 12-1/4 cents at $11.80-1/4 per bushel.
