Timeline of 1389

Chûzan enters into diplomatic relations with Goryeo (Korea).
Ming Dynasty China informs Korea that the Ssanggyeong region, controlled up until recently by the Mongol Empire (and thus by the Yuan Dynasty of China), is Ming territory. A military conflict results which ends in the fall of Goryeo and the establishment of the Joseon Dynasty in 1392.
