* U.S. harvest set to bring ample supplies to market

* Wheat rebounds from near three-month low

SYDNEY/PARIS, Aug 30 (Reuters) - U.S. corn and soybeans were flat on Wednesday in markets torn between strong demand and large global supplies, including approaching U.S. harvests, while wheat rebounded from a near three-month low. The most active corn futures on the Chicago Board of Trade were unchanged at $3.48-3/4 a bushel by 1134 GMT, having closed down 0.9 percent in the previous session when prices hit $3.47 a bushel, the lowest since Dec. 27, 2016. Analysts said corn was under pressure from the approaching U.S. harvest that is expected to keep the market well supplied, despite dry weather earlier in the season. Fears of potential shortfalls in U.S. output have receded in recent weeks after earlier dry weather. The U.S. Department of Agriculture (USDA) said 62 percent of the U.S. corn crop was in good to excellent condition, unchanged from last week. Capping losses, analysts said, was recent strong export demand and potential delays in harvesting in the Mississippi River Delta region. The USDA said on Tuesday exporters sold 226,000 tonnes of U.S. corn to Mexico. The most active soybean futures contract was also unchanged at $9.37-1/4 40 a bushel, after rising to $9.41 a bushel in earlier trade. It closed down 0.4 percent on Tuesday. Analysts said soybeans were drawing support from concerns about potential delays in U.S. shipments because of Tropical Storm Harvey, while recent U.S. sales also aided sentiment. The USDA said 198,000 tonnes of U.S. soybeans were sold to China. In other grains markets, wheat rose as prices rebounded from a near three-month low. The most active wheat futures were up 0.6 percent to $4.32-1/4 a bushel, having closed up 0.4 percent on Tuesday after earlier hitting a low of $4.22-1/2 a bushel - the lowest since June 1.
