Private exporters reported China bought 486,000 metric tons of 2014/2015 soybeans, most of which are U.S. soybeans, and Nigeria bought 101,000 of 2014/2015 U.S. wheat, USDA said on Monday.

Of China's total, 66,000 will be optional-origin soybeans. An optional origin contract provides that the origin of the commodity may be the U.S. or one or more other exporting countries.

Nigeria's purchase includes 61,000 tonnes of hard red winter wheat and 40,000 of soft red winter.

The marketing year for wheat began June 1 and the marketing year for soybeans begins Sept. 1.
