Chinese Diplomatic Mission to Rome
Persian Gulf (also known as thIn 97 CE, the Han Chinese general Ban Chao, the Protector-General of the Western Regions, sent his emissary Gan Ying on a diplomatic mission to reach the Roman Empire. Gan visited the court of Pacorus II at Hecatompylos before departing towards Rome. He traveled as far west as the Persian Gulf, where Parthian authorities convinced him that an arduous sea voyage around the Arabian Peninsula was the only means to reach Rome. Discouraged by this, Gan Ying returned to the Han court and provided Emperor He of Han (r. 88–105 CE) with a detailed report on the Roman Empire based on oral accounts of his Parthian hosts. William Watson speculates that the Parthians would have been relieved at the failed efforts by the Han Empire to open diplomatic relations with Rome, especially after Ban Chao's military victories against the Xiongnu in eastern Central Asia.
