Island tourism has always been one of the most attractive kinds of tourism globally. However, it is challenging to analyze tourist development on an island since it is a dynamic entity with unique characteristics. In recent years, island tourism development has faced some challenges, such as climate change, environmental degradation, economic downturns, cultural erosion, and diseases like the COVID-19 pandemic. Thus, sustainable development is key to ensuring the destination can keep up with demand. The author opted for the SLIQ concept as a new approach while seeking innovative ways to tackle old problems. The paper selected Hai Tac Islands, Vietnam, as a case study, using qualitative research and conducting in-depth interviews with six residents. The findings showed that local authorities should govern the island as living entity requiring a distinct way of thinking because island destinations are susceptible to economic perils and environmental issues. The paper also confirmed that sustainable economic growth, environmental protection, and human fairness should be the three goals of public policy when it comes to planning and managing inclusive tourism island development.
