In 124, Kucha formally submitted to the Chinese court, and by 127 China had conquered the whole of the Tarim Basin. China's control of the Silk Road facilitated the exchange of art and the progation of Buddhism from Central Asia. The Roman Maes Titianus is known to have visited the area in the 2nd century AD, as did numerous great Buddhist missionaries such as the Parthian An Shigao, the Yuezhis Lokaksema and Zhi Qian, or the Indian Chu Sho-fu (竺朔佛). The Han controlled the Tarim states until their final withdrawal in 150 AD.
