RESUMEN
This article aims at writing a research framework for exploring sustainable cultural heritage tourism policy implementation at Angkor (World Heritage Area). There are six policy initiatives within Angkor's Tourism Management Plan (2012-2020) to guide sustainability of tourism development. The year 2020 was the end of implementing these policy initiatives, but there were not any documents reporting the effectiveness and success of their implementations; therefore, this study will show the framework for investigating the implementation of policy initiatives within this timeframe. There are three main objectives in this framework. First, it is necessary to identify the outcomes of policy implementation judged by stakeholders. Second, it is important to outline and understand the barriers that hinder the successful implementation of the policy. Third, there is a need to create a framework for how to successfully implement sustainable tourism policies in the development of more sustainable tourism in the future.
