GRAINS-Soybean up on strong demand, eyes potential U.S. trade war

* Brazil to boost soybean exports as drought cuts Argentina supply

* Wheat up in technical buying after sharp drop earlier in week

(Updates prices, adds details, quotes, changes dateline) SINGAPORE/PARIS, March 22 (Reuters) - Chicago soybeans futures rose for a third consecutive session on Thursday, supported by strong demand, and traders waited to see if U.S.-China trade tensions would hit the sector. Corn extended gains in the previous sessions while wheat also rose for a third session, although it failed to recover all the losses recorded on Monday when it hit a one-month low on prospects of more rains in the parched U.S. winter crop areas. The most-active soybeans contract on the Chicago Board Of Trade rose 0.3 percent to $10.32-1/2 a bushel, having firmed 0.1 percent on Wednesday. Corn added 0.5 percent to $3.77 a bushel, having closed up 0.1 percent in the previous session. Wheat was up 1.2 percent to $4.58-3/4 a bushel by 0254 GMT. Prices dropped to lowest since February 22 at $4.46-3/4 a bushel on Tuesday before closing marginally higher. The U.S. Department of Agriculture said it would delay the release of its weekly U.S. export sales report by a day to Friday at 8:30 a.m. EDT (1230 GMT) due to inclement weather delays in the Washington, D.C., area. Worries about the impact of a potential trade war on U.S. grain and soy exports hung over the market, capping rallies, as U.S. President Donald Trump prepares to announce up to $60 billion in import duties on Chinese goods. The U.S. Department of Agriculture's attache in China put soybean imports in the 2018/19 season at 100 million tonnes, up from 97 million in 2017/18. "(China) is likely to switch as far as possible to alternative suppliers such as Brazil and Argentina though the drought-related crop outages in the latter are likely to make this more difficult," Commerzbank said in a note. Brazil's soybean farmers are poised to export a record volume of the oilseed this year as a drought reduces supplies from neighbouring Argentina, André Pessoa, founding partner of consultancy Agroconsult, said on Tuesday. Wheat rose on technical buying after a slump earlier in the week as weather forecasts suggested further showers across the southern Plains, potentially boosting crops. Meanwhile, India dropped a plan to double a wheat import tax to 40 percent, two government sources said, in a sign it expects imports to make up for a shortfall in domestic production for the third year in a row. Prospects of a large crop in Russia, one of the world's largest grain exporters, also weighed on the market with reports that winter grain sowings had survived the winter well, with only 3 to 5 percent in poor condition. Commodity funds were net buyers of CBOT soyoil, soybean, soymeal and corn futures on Wednesday and net sellers of wheat, traders said. Prices at 1157 GMT
