A growing wave of soybean imports appears to make China increasingly dependent on U.S. supplies. Last market year, one out of every four rows harvested was bound for China. In the new market year, nearly two out of every three bushels of soybeans sold by U.S. exporters has a Chinese destination.

China produced fewer than 500 million bushels (mbu) of soybeans but imported 2.1 billion bushels – a record 895 mbu of which came from the U.S. Meanwhile, U.S. corn farmers have finally begun to see long-anticipated corn sales into China. But could this change? Could current efforts to modernize its farm sector make China less import-dependent?

“China is the big 'x-factor' in world agricultural markets right now,” says Tom Sleight, CEO for the U.S. Grains Council. “It’s not a question of who is involved [in modernizing], but of who isn’t.”

China is attracting investments by large, global organizations, says Ken Golden, director of public relations for Deere & Company. “The country is also encouraging mechanization and improved farming practices.”

Deere now has more than 5,000 employees in China, eight manufacturing facilities, a research and development center and a large supplier network providing low-, mid- and high-horsepower tractors, combines and diesel engines.

Seed companies are collaborating with the Chinese government, academia, other industries and Chinese farmers to develop better genetics. Last February, DuPont Pioneer signed a multi-year agreement with the Beijing International Flower Port to build a state-of-the-art technology hub that will develop new high-yielding corn hybrids for China.

China is “rapidly adopting new technologies, improved agronomic practices, and mechanization,” says William Niebur, DuPont vice president and general manager for DuPont Pioneer China.

“The Chinese policy is to be 95% self-sufficient in strategic commodities like corn and pork,” explains Sterling Liddell, vice president of food and agricultural research for Rabo Agri Finance. That policy pushes China to maximize domestic corn production rather than soybeans, while at the same time an expanding, evolving hog industry is increasing China’s soybean usage.

A decade ago, 70% of China’s hogs were raised in backyards, Liddell says. “Now close to 70% are raised in confinement, and that means they need more corn and soybeans.”

A shift to emphasize domestic soybean production at the expense of corn acres would require a major switch in Chinese central policy, Liddell says. “In the long run, could they switch to be more oilseed-friendly? They could, but it is unlikely. They need grain just as much as they need beans.”

In the corn sector, China’s yields have been climbing steadily, from about 50 bu./acre in 1980 to 95 bu./acre by 2010-2011, and Niebur believes China’s approval of biotech-enhanced corn could shift the trend line up even faster. Achieving 95% self-sufficiency is, however, “highly dependent on population growth and overall consumption rates that are also increasing exponentially,” he says.
