UNESCO has always been closely linked to philosophy, not speculative or normative philosophy, but critical questioning which enables it to give meaning to life and action in the international context. UNESCO was born from a questioning process on the possibility of and necessary condi­tions for the establishment of long-term peace and security in the world. One could also de­clare that it is a philosophical institution, since it intends to contribute to maintaining peace and security by heightening collaboration between nations through education, science and culture in order to ensure the universal respect of justice, of the law, of human rights and fundamental liberties for all, regardless of race, gender, language or religion.

In Cambodia, UNESCO works to create a Culture of Peace—a set of values, attitudes, and ways of life that reject violence and prevent conflicts among individuals, groups and nations by tackling their root causes through dialogue and negotiation. UNESCO Office in Phnom Penh works in close cooperation with the Cambodian government, ministries and public/private academic institutions to keep philosophy relevant for the develop­ment of Cambodia. The Philosophical Association of Cambodia (PAC) and the Royal Academy of Cambodia, in collaboration with UNESCO Office in Phnom Penh, have held conferences and forums, and have celebrated the World Philosophy Day every year to mark the importance of philosophical reflection and to encourage the Cambo­dian people to preserve their philosophical heritage.
