During the Five Dynasties and Ten Kingdoms period of China (907–960), while the fractured political realm of China saw no threat in a Tibet which was in just as much political disarray, there was little in the way of Sino-Tibetan relations. Few documents involving Sino-Tibetan contacts survive from the Song dynasty (960–1279). The Song were far more concerned with countering northern enemy states of the Khitan-ruled Liao dynasty (907–1125) and Jurchen-ruled Jin dynasty (1115–1234).
