On Yuan Chwang's Travels in India, 629–645 A.D. v1.c7.s5.16

v1.c7.s5.16

This king was the head of the Shao-wu clan and the name of the particular branch to which he belonged was Wên (溫).¹ The Western Turks had at this time gained the ascendancy in these regions and had become all-powerful. Policy and ambition made this king wed a daughter of the Turkish royal family and the result was that the Samokan (K‘ang) country became a vassal to the West Turks. In the year A.D. 631 the king sent an embassy to China praying to be received as a vassal, but the Chinese Emperor for wise and patriotic reasons declined to accede to the request.²
