This is part 1 of a 2-part series covering the history of the relations between China and Cambodia. In this first half of the series, I present the early history. Some of this material was covered in the China-Vietnam series: Funan, Zhenla, and the Khmer Empire. This is a nice refresher if you forgot about that. Cambodia didn't have the same historical relations with China as their two neighbors and sometimes antagonizers, Thailand and Vietnam. A lot of what happened later on, in Part 2, had its roots in mid-19th century Cambodia. I hope this episode is useful as an intro to Cambodian history. We'll take things up to 1965 here and finish off next time.
