Reuters factbox reviews China's historical U.S. agricultural purchases. Soybeans made up over half of China's U.S. farm buys in 2017, and China was a major corn buyer only in 2011-2013.
China has purchased about 10 million tonnes of soybeans since September 1 and has made no firm commitment on amounts.
Background on past buying patterns helps gauge how much new demand the phase one deal can add for soybeans, corn and rice, with soybeans the main price driver.
After 250 past neutral trade events, Soybeans moved a median +0.0% over 5 sessions (50% higher; middle half -1.4% to +1.6%), and -0.2% over 20.
After 480 past neutral trade events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
