Chicago Board of Trade soyabean futures ended near unchanged on Wednesday as rising supplies from an accelerating US harvest overshadowed optimism that China, the world's top soya importer, would ramp up US purchases, traders said.

CBOT November soyabeans settled 1/4 cent lower at $9.33-3/4 per bushel.

CBOT December soyameal ended $1.70 higher at $308.60 per short ton, while December soyaoil fell 0.27 cent to settle at 30.58 cents per pound.

Beijing on Tuesday offered soyabean processors waivers that would exempt them from tariffs on imports of up to 10 million tonnes of US soyabeans. The waivers, however, have not unleashed a torrent of purchases.

The US Department of Agriculture on Wednesday confirmed private sales of 128,000 tonnes of US soyabeans to undisclosed buyers, widely believed to be China. Hedge selling and rising supplies from an accelerating US harvest weighed on futures prices. Mostly dry weather forecast for much of the US farm belt over the next two weeks should ramp up harvesting.
