Qilibi Khan (died 645?

), personal name Ashina Simo (also known as Li Simo, full regal title Yiminishuqilibi Khan, Tang noble title Prince of Huaihua), is a member of the Eastern Tujue (Göktürk) royal house who is given the title of Khan of Eastern Tujue for several years, as a vassal of the Chinese dynasty Tang Dynasty.

After Emperor Taizong of Tang conquers Eastern Tujue in 630, he briefly settles the Eastern Tujue people within Tang borders, but after a failed assassination attempt against him by a member of the Eastern Tujue royal house, Ashina Jiesheshuai in 639, he changes his mind and decides to resettle the Eastern Tujue people between the Great Wall and the Gobi Desert, to serve as a buffer between Tang and Xueyantuo.

He creates Ashina Simo, a member of Eastern Tujue's royal house as well, as Yiminishuqilibi Khan (or Qilibi Khan for short), and Ashina Simo serves as the khan of the recreated Eastern Tujue khanate for several years.

However, in 644, faced with constant pressure from Xueyantuo, Ashina Simo's people abandon him and flee south back to Tang territory.

Ashina Simo himself also returns to Tang and serves as a Tang general until his death, probably in 645.
