GRAINS-Soybeans higher as U.S.-China jitters ease, Argentina stays dry

* Soybeans touch one-week high in moderate rebound

* Investors see signs of lessening U.S.-China trade tension

* Forecasters still cutting Argentina crop outlook

* Corn also firm, wheat eases after one-week high

(Updates with European trading, changes byline/dateline) PARIS/SINGAPORE, March 26 (Reuters) - Chicago soybeans rose on Monday as concerns over trade tensions between China and the United States eased, shifting attention back towards crop damage in Argentina. Corn also firmed, while wheat edged lower after touching a one-week high as investors assessed the impact of rain in parched U.S. growing belts. The Chicago Board of Trade's most-active soybean contract gained 0.5 percent to $10.33-1/2 a bushel after hitting a one-week peak of $10.40-1/4. Soymeal, of which Argentina is the world's biggest exporter, was up 1 percent at $381.8 a tonne. Soybean futures had slipped on Friday as traders feared an escalating trade dispute between the United States and China would disrupt soybean flows between the world's biggest producer and the world's largest importer of the oilseed.

But investors took comfort on Monday from reports that the two countries may enter trade talks, helping share prices to rebound. In Argentina, crop analysts were continuing to lower their harvest outlook because of dry weather and meteorologists said recent rain was scattered and may have limited benefit to crops as harvesting approaches. "The weather window in Argentina (is) rapidly closing as crops enter into late grain-fill and full-maturation stages," Thomson Reuters Agriculture Research analysts said in a note. The Buenos Aires grains exchange last week cut its estimate of the country's soy harvest to 39.5 million tonnes from 42 million tonnes previously. CBOT corn was up 0.4 percent at $3.78-3/4 a bushel, tracking soybeans. It also touched a one-week peak earlier in the session at $3.80-3/4. Like soybeans, corn is among agricultural products imported by China and a major crop grown by Argentina. Market attention was turning towards this Thursday's U.S Department of Agriculture (USDA) plantings report, with rising expectations that soybeans will overtake corn in acreage this year. CBOT wheat ticked down 0.4 percent to $4.58-1/4 a bushel after hitting a one-week high at $4.63-3/4. Traders were assessing rainfall in the U.S. Plains to see if it would improve the condition of parched winter wheat crops. The return of rain last week helped to push futures lower. "U.S. hard red winter (HRW) wheat crops remain at risk of falling yields," said Tobin Gorey, director of agricultural strategy at Commonwealth Bank of Australia. "The HRW crop regions did get a little rain last week but not enough where it was most needed." The Commodity Futures Trading Commission's weekly commitments of traders report on Friday showed that non-commercial traders -- a category that includes hedge funds -- increased their net short position in CBOT wheat and cut their net long position in corn and soybeans in the week to March 20.
