[The _Korea Review_ publishes a _History of Korea_ based upon Korean and Chinese sources, from which we gather some interesting facts regarding the relations of China, Korea, and Japan at the time of Kúblái: “In 1265, the seed was sown that led to the attempted invasion of Japan by the Mongols. A Koryŭ citizen, Cho I., found his way to Peking, and there, having gained the ear of the emperor, told him that the Mongol powers ought to secure the vassalage of Japan. The emperor listened favourably and determined to make advances in that direction. He therefore appointed Heuk Chŭk and Eun Hong as envoys to Japan, and ordered them to go by way of Koryŭ and take with them to Japan a Koryŭ envoy as well. Arriving in Koryŭ they delivered this message to the king, and two officials, Son Kun-bi and Kim Ch’an, were appointed to accompany them to Japan. They proceeded by the way of Kŏje Harbor in Kyŭng-sang Province, but were driven back by a fierce storm, and the king sent the Mongol envoys back to Peking. The Emperor was ill satisfied with the outcome of the adventure, and sent Heuk Chŭk with a letter to the king, ordering him to forward the Mongol envoy to Japan. The message which he was to deliver to the ruler of Japan said, ‘The Mongol power is kindly disposed towards you and desires to open friendly intercourse with you. She does not desire your submission, but if you accept her patronage, the great Mongol empire will cover the earth.’ The king forwarded the message with the envoys to Japan, and informed the emperor of the fact.... The Mongol and Koryŭ envoys, upon reaching the Japanese capital, were treated with marked disrespect.... They remained five months, ... and at last they were dismissed without receiving any answer either to the emperor or to the king.” (II. pp. 37, 38.) Such was the beginning of the difficulties with Japan; this is the end of them: “The following year, 1283, changed the emperor’s purpose. He had time to hear the whole story of the sufferings of his army in the last invasion; the impossibility of squeezing anything more out of Koryŭ, and the delicate condition of home affairs, united in causing him to give up the project of conquering Japan, and he countermanded the order for the building of boats and the storing of grain.” (II. p. 82.)
