Rush hour in Ho Chi Minh City Photo Credit: Double-A Rush hour in Ho Chi Minh City Cambodian historian David Chandler has attributed the loss of the Khmer region to Cambodia. First of all, the loss of Porenoco symbolized that the Khmer people lost the opportunity to participate in maritime trade, and fewer merchants and missionaries went deep into Cambodia in the age of sailing and left valuable records to record their history.

Since then, the only deep-water port of Cambodia's state-owned commercial value is Sihanoukville, but the development of the latter is hundreds of years later than that of Porenogo, and it is even less strategic.

Also because of this background, when Vietnam invaded Cambodia at the end of 1978 and defeated the notorious "Khmer Rouge" , although it rescued many people who almost lost their lives due to genocide, this round of Vietnam's invasion also caused "national shame". "Recovery." The leader of the Khmer Rouge, Pol Pot, once called people in the eastern provinces "Khmer skin and Vietnamese bones" during the Democratic Kampuchea period, so be careful. And this kind of hatred for Vietnam is more likely to be provoked in Cambodia. In any case, during the period of the loss of the Lower Khmer region and the demise of the Champa regime in the 17th and 18th centuries, Cambodia finally lost its "buffer zone of power" and had to face the two major powers in.
