The rationale expressed by "gyorin" was applied to a multi-national foreign policy. Scholarly writing about the Joseon dynasty has tended to focus on diplomatic relations with China and Japan, but the intermediary nature of "gyorin" contacts—for example, Joseon-Ryukyuan diplomatic and trading contacts—were important as well.
