A new consolidation of the Turk, under the Western Turk ruler Tardu, again threatens China for a brief period at the beginning of the seventh century.

In 601 Tardu's army besieges Chang' an (modern Xi'an), at this time the capital of China.

Tardu is turned back, however, and, upon his death two years later, the Turk state again fragments. The Eastern Turk nonetheless continue their depredations, occasionally threatening Chang'an.
