Most interestingly, documents in mainland China written by agents of the Wu emperor about AD 250 appear to have described Oc Eo as a sophisticated country (Funan) ruled by a king in a walled palace, complete with a taxation system. The Funan culture is the precursor to the flowering of the Angkor Civilization.
Recent investigation into the canals at Oc Eo suggest that they once connected the city with the capital of Angkor Borei, the agrarian capital of the Funan culture, and may well have facilitated the remarkable trade network spoken of by the Wu emperor's agents.
