Like his father, Pacorus continued the same policies of the prominent former Parthian king Artabanus II (r. 12 - 38/41), which included increasing the economic sources of the Parthian Empire by establishing a new trade system and strengthening relations with other powers, such as Han China. Parthian interest also continued to grow in eastern lands of Khwarazm, Bactria, and the Hindu Kush. The influence of the Parthians is demonstrated by the existence of their aspects in the coinage of numerous political entities in those areas.
