Japan invited collaboration with China, while Korea was conquered by China.

Explanation:

Japan, China, and Korea had a long history of frequent conflict.

However, the Chinese-Japanese friendly contact started through trade, and eventually, the Chinese influence over Japan grew because the Japanese imperials adopted many Chinese customs. Very different is the case of Korea, which was conquered by China before having their influence spread on their customs.
