and called it Nanjing (南京 literally: "Southern Capital"). His domain extended north to Laoyeling Mountains, south to Hamgyŏngnamdo in modern-day North Korea, east to the Sea of Japan and west to the Zhangguangcailing Mountains, corresponding to the borderlands of modern-day China, Russia and North Korea. He seems to have submitted to the Mongol Empire again. In 1218 the Mongol and Eastern Xia armies jointly intruded into Goryeo to subdue the Khitan remnants. Goryeo also joined the campaign and the Khitans were exterminated. The Mongol army retreated after establishing a "sibling" relationship with Goryeo. Mongol officers with Eastern Xia delegates came to Goryeo to exact tribute. In 1222 Puxian Wannu revolted against the Mongol Empire yet again while Genghis Khan made an expedition toward the west. Since Goryeo rejected his demand for the opening of trading posts on the border, he invaded Goryeo many times. In 1233 Ögedei's son Güyük attacked Eastern Xia with a large force and captured Puxian Wannu. The Jin dynasty was overthrown in the next year.
