What real life continent or land is Kunark based on?

It seems geo-societal feature of Kunark is mostly from jungle civilizations of indo-sumatra region. It is almost identical in many parts, including those Asian-like structures inside CoM.
They also have a Lizard-looking mythical creatures in their mythology said to be inhabitted deep in the Jungle, have their own civilization.

Ofcourse Kunark is not just that(even if my assumption is correct), as someone said those white marble structures are obvious staple from Greece culture
