King Gojong called foreigners "uneducated louts," motivated by "lechery and sensuality." The Joseon Dynasty was widely referred to as a "hermit kingdom" for sealing itself off from foreign influence. Joseon diplomacy mainly involved the "Sadae" ("serving the great") policy toward Imperial China. Concurrently maintained (and jointly referred to as "serving the great and relations with neighbor policy" ) was the "Gyorin" policy of amicable relations with neighbouring countries; however this did not result in significant influx of foreign persons but rather sporadic trade delegations and diplomatic missions: envoys from the Ryūkyū Kingdom were received by Taejo of Joseon in 1392, 1394 and 1397. Siam sent an envoy to Taejo's court in 1393.
