After the battle, peace negotiations followed and the Liao dynasty did not invade Korea again. Korea agreed to break off relations with the Song and have tributary relations with the Liao, but kept its newly gained territories at the Yalu river. According to historian Bielenstein however, Goryeo maintained diplomatic relations with Song rather than break relations,
Hyeonjong kept his own reign title, and the Goryeo and Liao had concluded peace as equals in 1022. After the conflict's end, Korea entered in a long and peaceful period with its foreign neighbours across the
Yalu River. ==See also==
