All countries around the world always wish to become the members of the Regions, Trade Blocks or others World Organizations in order to develop their own country. Besides, Cambodia is a country which has a lot of temples and many beautiful places. The royal government of Cambodia had tried all the best to integrate itself to become those members.

Recently, Preah Vihea has introduced into the World Heritage on 07 th July, 2008 at Quebee, Canada which was prepared by UNESCO and unanimity supported by other twenty one country member.

First of all, we want the world to acknowledge internationalizedly. After Preah Vihea becomes the World Heritage .people around the world will know and they'll come and visit our country especially Prasat Preah Vihea, so we can get many benefits from those tourists.

Second, we want to glorify our culture values on the international stages. Absolutely, the world will know that Cambodia is the country of temples, sculptures, shrine places and other landscapes. They will spread to the world what they have seen in Cambodia when they are back to their own home country. More or less the number of tourists in our country will be increasing.

Finally, we want the international to support and preserve or conserve to be better. UNESCO will use their fund to conserve the temple and the environment around the Preah Vihea or they will send their observers to watch what we have done after they introduced our temple into the World Heritage
