Is it possible for more centralised and partially agricultural states to arise in Siberia and North East Asia. By Siberia and North East Asia, I specify those parts that are hospitable for seasonal agriculture, Like South Siberia and Manchuria, and not the Arctic. The nomadic empires, although having agricultural and some cities were not sufficiently centralised. One examples could be Liao and Jin empires in North East Asia and Manchuria. However they had a large Chinese populations and Chinese bureaucratic apparatus that helped in centralisation, despite Khitans of Liao still being nomadic. Is it possible for indigenous and centralised states to arise in this region, or it is only possible for the strong but decentralized semi-Nomadic empires to do so? Is the region itself not hospitable for such a state structure? If it is possible then how can states like that arise?
