The Cambodian National Sustaining Party was created by its president Pen Sovan.

Another left-wing idea is promoting peoples interests in the present and future.

The other part of its ideology is liberalism since the CNSP believes in "peace", "freedom", opposition to "anarchism", "dictatorship" and prevent "starvation and poverty" in Cambodia, and construct a "free and pluralistic democracy".

This is because the Cambodian National Sustaining Party wanted to protect democracy and safety of political party candidates for a free and fair 2002 February election.
