These two areas lie towards the eastern side of the present location of India.
Khambojas are spoken highly and they had a say in running of the fifty six kingdoms of India.

History of Khambhoja is more ancient.
Cambodia was founded by Kaundinya from Kanchipuram, India.

This surmise is due tò the fact that the Khmer dynasty was preceded by Funnan dynasty and its reference is found ancient texts.
And the fact that Jayavarman II who is described as the King of Khmer was A Tamil.(802–850)
He was preceded by Funnan Dynasty about which no information is available, save from Indian texts.
Chinese texts are silent on this subject.
And there seems to be A Tamil connection as well.
Current evidence at 8 Century may be pushed back due to the date of Ramayana as 5114 BC.

The Khmer Empire (; Khmer: Chakrphup Khmer or Anachak Khmer), officially the Angkor Empire (Khmer: Anachak Angkor), thepredecessor state to modern Cambodia (“Kampuchea” or “Srok Khmer” to the Khmer people), was a Hindu–Buddhist empire inSoutheast Asia. The empire, which grew out of the former kingdoms of Funan and Chenla, at times ruled over and/or vassalised most of mainland Southeast Asia and parts ofSouthern China, stretching from the tip of the Indochinese Peninsula northward to modern Yunnan province, China, and from Vietnam westward to Myanmar.‘
The “Kingdom of Cambodia” is the official English name of the country. The English “Cambodia” is an anglicisation of the French “Cambodge”, which in turn is the French transliteration of the Khmer kampuciə. Kampuchea is the shortened alternative to the country’s official name in Khmer prĕəh riəciənaacak kampuciə. The Khmerendonym Kampuchea derives from the Sanskrit name kambojadeśa, composed of deśa (“land of” or “country of”) and kamboja, which alludes to the foundation myths of the first ancient Khmer kingdom
