sentences:  The short-lived Sui dynasty (581–618 AD) reinvaded Annam (northern Vietnam) and attacked Champa (southern Vietnam), while they also attempted to conquer Korea, which failed (see Goguryeo-Sui Wars).The later Tang dynasty (618–907) aided the Korean Silla Kingdom in defeating their two Korean rivals, yet became shortchanged when they discovered Silla was not about to allow the Tang to claim much of Goguryeo's territory (as it had been under the Chinese Han dynasty's control a few centuries before, the Han having wrested it from native kingdoms at that time).The Tang Dynasty established control over the Tarim Basin region as well, fighting wars with the new Tibetan Empire and stripping them of their colonies in Central Asia (which was abandoned after the An Lushan Rebellion).
