Abstract
This paper aims to investigate the bases for the existing cooperation in the field of agricultural activities among the Northeastern Asian economies comprising Japan, Korea, Taiwan, and China. The main results are as follows: the first cooperation basis stems from the fact that all the four abovementioned economies are located in the Asian monsoon area, and thus have a similar agricultural structure that is based on rice plantation. The second basis is the economic features of a high income economy and pure food import. Currently, only China does not fulfill this condition. The possibility that China will fulfill it after becoming an advanced economy is not unlikely. The last basis is the intimate food network operating among the above economies, which has shown steady increase over the last two decades. The issue of food security, including production process monitoring, that emerged in 2008 regarding food exported from China has also been a factor that has strengthened the food network.
