With the slowdown of the world economic growth in 2015，a negative growth in international trade was witnessed. In the same period，China’s total imports and exports of agricultural products dropped by 3.5%，of which its exports fell by 1.6%，and its imports fell by 4.6%. China’s agricultural trade deficit continued to decrease. With the increase of domestic grain production during the past eleven consecutive years，the grain imports yet increased by 67.6%. Particularly，the imports of corn，rice，wheat and sorghum increased remarkably. The main reason for China’s negative growth in international trade is owing to a continuous increase in domestic food prices，a lack of consumption demands，and the sluggish recovery of the world economy. The continuous increase in China’s grain imports was on account of a continuous and rigid rise in domestic grain prices，which contrasted sharply with the rapid decrease in international grain prices. With the existence of a series of uncertain factors，the global economic growth in 2016 will not be optimistic.
