In sites such as Angkor, tourism is inevitable. Therefore, the site management team cannot exclusively manage the site. The team has to manage the flow of people. Millions of people visit Angkor each year, making the management of this flow vital to the quickly decaying structures. Western tourism to Angkor began in the 1970s. The sandstone monuments and Angkor are not made for this type of heightened tourism. Moving forward, UNESCO and local authorities at the site are in the process of creating a sustainable plan for the future of the site. Since 1992, UNESCO has moved towards conserving Angkor. Thousands of new archaeological sites have been discovered by UNESCO, and the organization has moved towards protected cultural zones. Two decades later, over 1000 people are employed full-time at the site for cultural sensitivity reasons. Part of this movement to limit the impacts of tourism has been to only open certain areas of the site. However, much of the 1992 precautionary measures and calls for future enforcement have fallen through. Both globally and locally the policy-making has been successful, but the implementation has failed for several reasons. First, there are conflicts of interest in Cambodia. While the site is culturally important to them, Cambodia is a poor country. Its GDP is marginally larger than Afghanistan's. Tourism is a vital part to the Cambodian economy, and shutting down parts of Angkor, the largest tourist destination in the country, is not an option. A second reason stems from the government's inability to organize around the site. The Cambodian government has failed in organizing a robust team of cultural specialists and archaeologists to service the site.
