The fourteenth century is an important turning point in the development of the history of various Northeastern and Southeastern countries such as China, Japan, Korea, Thailand, and Indonesia, particularly in the history of the trade there. Against the background of this period, a certain Chen Yan Xiang, apparently a Chinese merchant, from Majapahit Kingdom in Java, Indonesia, visited Joseon Kingdom in Korea between the late fourteenth century and the early fifteenth century. His visit is recorded only in the Korean historical document Joseon Wangjo Sillok. This paper which deals with the contact between Joseon and the kingdom of Majapahit between the late fourteenth century and the early fifteenth century will provide an opportunity to look into an aspect of the trade that the ancient kingdom in Indonesia conducted with East Asia in this period, particularly the trade in which the Chinese merchants in Java were engaged in the South China Sea and the East China Sea. And this study will make it possible to see a side of an attitude on the part of Korea toward foreign trade in this period, and will demonstrate that Japanese pirates' threat was significantly attributable to the failure for the exchange between Korea and Java to develop any longer after the early fifteenth century.
