* Wheat rebounds after losing more than 1 pct in prior session

* Soybeans firm as U.S.-China trade tensions ease

* Corn edges higher

PARIS/SYDNEY, Dec 17 (Reuters) - U.S. wheat futures rebounded more than 1 percent on Monday after a sharp fall in the previous session, as a jump in prices in top exporter Russia improved U.S. wheat's competitiveness on world markets. Soybeans rose 0.5 percent, rebounding from an eight-day low touched in the previous session, as signs of easing trade tensions between Washington and Beijing supported gains. Corn edged higher, following wheat. The most-active wheat futures on the Chicago Board of Trade were up 1.2 percent at $5.36-1/4 a bushel by 1147 GMT, having closed down 1.1 percent on Friday. "The steadiness of Black Sea prices is spreading to all markets and recent rains in Argentina are increasing the fears to see a qualitative degradation of the wheat crop in the country," French consultancy Agritel said in a note. Russian wheat export prices rose sharply last week after global benchmark Chicago wheat futures hit their highest in nearly two months and domestic supply declined due to seasonal factors, analysts said on Monday. Prices were also supported by mounting concern in the global market that Russia could limit exports later in the season. However, the risk of export curbs has eased since October as shipments slowed. Russia's grain exports are up 4 percent so far this marketing year, which started on July 1, compared with 40 percent in early September. Soybean futures were up 0.5 percent at $9.04-3/4 a bushel, having closed down 0.7 percent on Friday, when prices hit $9.00 - the lowest since Dec. 6. Analysts said the market was buoyed by expectations that China will buy large amounts of U.S. exports as part of a temporary truce in the trade war between the two. "U.S. soybean exports are likely to benefit from easing U.S.-China trade tensions," said Tobin Gorey, director of agricultural strategy, Commonwealth Bank of Australia. The U.S. Department of Agriculture (USDA) on Thursday confirmed 1.13 million tonnes of U.S. soybeans had been sold to China, and on Friday confirmed another 300,000 tonnes sold to China plus 130,000 tonnes sold to unknown destinations.

The most-active corn futures were 0.3 percent higher at $3.85-3/4 a bushel, having gained 0.1 percent in the previous session.
