Chicago Board of Trade (CBOT) grains futures closed higher on Thursday with corn futures climbing to a one-week high on bargain buying and improving export demand.

Soybeans rose for a second day and notched a two-week high as expectations of lower U.S. yields and rising demand from overseas buyers supported the market, while wheat rebounded from six straight lower sessions.

The most active corn contract for December delivery rose 2.25 cents, or 0.65 percent, to 3.505 dollars per bushel. December wheat delivery added 8 cents, or 1.91 percent, to 4.26 dollars per bushel. January soybeans went up 8 cents, or 0.81 percent, to 9.9925 dollars per bushel.

According to data released by the U.S. Department of Agriculture (USDA) on Thursday, 1,356,360 tonnes of U.S. corn will be sold to Mexico in the current and next marketing years. The marketing year for corn began Sept. 1.

The USDA will update its official U.S. crop production estimates in a monthly report next week.
