Map of Asia around 603: the Western Göktürk Khaganate from the Black Sea to the Tian Shan and the Eastern Göktürk Khaganate from the Khangai to the Khitan, the Tarim oasis states and the Hephthalite principalities as tributaries of the west, beside the Eastern Roman Empire, Sasanian Persia, the Sui, the Tuyuhun and Goguryeo, and between the steppe and China the wall of the Northern Qi, Yami's pasture in the Ordos and a hatched frontier zone
The khaganate divided around 603: the Western Göktürk Khaganate from the Black Sea to the Tian Shan and the Eastern Göktürk Khaganate from the Khangai to the Khitan, beside the Sui, now ruling all of China, Sasanian Persia and the Eastern Roman Empire. Between the steppe and China stand the wall of the Northern Qi (556) and a frontier zone held by neither side. The Baidao plain belongs to the Göktürks, and the north of the Ordos is Yami's pasture. Modern map; the line between east and west is approximate.
