Su Wu
Considering that Qiedihou would look favourably on China, the Han Emperor decided to try and achieve his goal of persuading the Chanyu to submit to China. The difficult economic situation in China, created by long struggles with northern, western and southern neighbours, prompted Emperor Wu to try to settle relations with the Xiongnu through peaceful negotiations. In 101 BC an embassy headed by Su Wu left for the Xiongnu loaded with rich gifts. However, contrary to Chinese expectations, Qiedihou was reported to be very arrogant, and the question of an allegiance was not even raised.
