The benchmark September 2010 soybean contract settled up CNY22, or 0.6%, at CNY3,867 a metric ton.
The dollar's weakness Friday and a strike by port workers in Argentina, which will slow soybean exports, both helped to support futures prices, analysts said.
Relatively strong performances Monday in other markets, such as metals, also helped to support sentiment towards agricultural products.
However, trading remained cautious in a tight CNY23/ton range ahead of a U.S. Department of Agriculture report to be issued Wednesday, which will give initial forecasts for acreage of major crops.
Cash soybean prices were slightly lower in very light trading, providing little trading guidance for futures.
Trading volume of all soybean contracts declined to 119,370 lots from 152,900 lots Friday.
Open interest fell 4,270 lots to 341,862 lots Monday. Futures for corn, soyoil, soymeal and palm oil all settled higher.
Following are Monday's settlement prices in yuan a metric ton for benchmark contracts and volume for all contracts in lots (One lot is equivalent to 10 tons):
