Joseon missions to the Ryukyu Kingdom

Joseon missions to the Ryukyu Kingdom were diplomatic and trade ventures of the Joseon dynasty that were intermittently sent after 1392. These diplomatic contacts were within the Sinocentric system of bilateral and multinational relationships in East Asia. The Ryukyuan King Satto established formal relations with the Joseon court.Kerr, George H. (1965). {{Google books|vaAKJQyzpLkC|Okinawa, the History of an Island People, p. 63.|page=63}}
