[economic Daily: continue to strengthen China's Corn Global supply chain] May 11, the Economic Daily article pointed out that in order to build a diversified pattern of corn import, we should focus on expanding corn import sources and optimizing import varieties, so as to avoid the security risks caused by too single import sources and import varieties. On the one hand, to expand the sources of imports, in addition to the United States and Ukraine, since last year, China has opened up channels for the export of corn to China from Myanmar, Brazil and South Africa. It is worth noting that in just a few months, Brazil has overtaken Ukraine to become the second largest source of China's corn imports. On the other hand, we should adjust and optimize the grain import structure and increase the import of corn substitutes such as barley, sorghum, wheat and broken rice, so as to effectively supplement the domestic corn gap. Food diplomacy has become an important part of China's diplomacy. Through active food diplomacy, we will continue to expand the "circle of friends", which will help to further strengthen the supply chain management capacity of the global food industry chain and grasp the initiative of international agricultural cooperation and food security.
